I've had a love affair with to-do lists for years. For a long time, the list was my shining sense of order amidst everyday chaos — proof that I had a grip on things. But the more I relied on it, the more I noticed something uncomfortable: I was ticking off tasks all day and still feeling like I hadn't moved forward. The hamster wheel was spinning, the checkmarks were accumulating, and yet the important things kept drifting to tomorrow.
The issue wasn't the list. It was how I was building it.
I work as a fleet chief officer on a passenger ferry operating the Dover–Calais route. The job generates tasks the way the English Channel generates waves — constantly, unpredictably, and with varying degrees of urgency. A to-do list that can't handle that environment is useless. Over time, through trial, error, and a fair amount of wasted effort, I've assembled a set of principles that turned my lists from a source of false comfort into something that actually drives results.
Not all to-do lists are created equal. Like any tool, their value depends entirely on how you wield them.
Eat the Frog
Mark Twain is often credited with saying that if you eat a live frog first thing in the morning, nothing worse will happen to you for the rest of the day. Whether he actually said it or not, the principle is rock solid: do your hardest, most dreaded task first.
The logic is simple. Willpower and focus are finite resources. They're at their peak early in the day, and they erode with every decision you make. If you spend your freshest hours answering emails and tidying up minor tasks, you'll arrive at the hard work already depleted. The frog — that one task you've been avoiding, the one that makes your stomach tighten when you look at it — should be the first thing you tackle.
I've found this especially true on board. The tasks I'm tempted to postpone are almost always the ones that matter most. Paperwork for port state inspections, safety audit preparation, complex crew scheduling decisions. None of them are pleasant to start. All of them are vastly easier to do at the beginning of a shift than at the end of one, when the day has already chewed through your concentration.
Eat the frog. The rest of the day feels lighter for it.
How to Eat an Elephant
The answer to the old riddle — "How do you eat an elephant?" — is one bite at a time. It sounds almost stupidly obvious, and yet most of us still stare at enormous tasks as if we need to swallow them whole.
When a task feels overwhelming, it's rarely because the work itself is impossible. It's because the scale of it triggers resistance. Your brain looks at the whole elephant and decides it would rather do literally anything else. The fix is to stop looking at the elephant and start cutting.
Break the task into pieces small enough that none of them, individually, feels threatening. Not "prepare for the annual audit" but "pull last year's deficiency reports," then "update the fire safety checklist," then "review crew certification expiry dates." Each of those is a task you can sit down and finish. The elephant disappears, replaced by a sequence of manageable bites.
This pairs naturally with eating the frog. Identify the hardest task, break it into pieces, and do the first piece before anything else. The two techniques together eliminate both the emotional resistance and the logistical overwhelm.
The Eisenhower Matrix and the Art of Triage
Dwight Eisenhower reportedly said that what is important is seldom urgent and what is urgent is seldom important. This observation led to the Eisenhower Matrix — a simple grid that sorts tasks into four quadrants: urgent and important, important but not urgent, urgent but not important, and neither.
The framework is well known. What I find less commonly discussed is how to actually use it under pressure, when you don't have the luxury of sitting down with a clean grid and thoughtfully placing tasks into boxes. In practice, I treat my to-do list more like a triage nurse treats an emergency room.
When a shift starts on a busy ferry, I don't have thirty minutes to meditate on priorities. I scan the list and sort fast. What will cause harm or serious consequence if it's not done now? That's urgent and important — it gets done first. What's important but can wait until this afternoon or tomorrow without consequence? That goes into the queue. What feels urgent but isn't actually important — the small fires that flare up and demand attention without deserving it? Those get delegated or deferred. And the rest — the tasks that are neither urgent nor important — get removed entirely.
The triage analogy works because it captures the speed and decisiveness the method requires. You're not curating a beautiful prioritized list. You're making rapid, clear-eyed judgments about where your time will have the most impact.
The Pareto Principle
The Pareto Principle — the 80/20 rule — suggests that roughly 80% of your results come from 20% of your efforts. Applied to a to-do list, this means that on any given day, a small handful of tasks are doing most of the heavy lifting. The rest is noise.
This was a hard lesson for me. I used to treat every task on the list as equally deserving of my attention. Checking off twelve items in a day felt productive. But when I looked honestly at what those twelve items actually accomplished, I'd find that two or three of them drove real progress and the rest were maintenance, busywork, or things that could have waited a week without consequence.
Now, before I start working through a list, I ask myself: which of these tasks, if completed, would make the biggest difference? Those are the 20%. Those get my best energy and my earliest hours. Everything else fills in around them — and if some of it doesn't get done, that's acceptable, because the high-impact work is already finished.
The Ivy Lee Method
In 1918, a productivity consultant named Ivy Lee was hired by Charles Schwab, then president of Bethlehem Steel, to improve efficiency. Lee's advice was disarmingly simple: at the end of each day, write down the six most important tasks for tomorrow. Rank them in order of priority. The next morning, start with task one and don't move to task two until it's finished. At the end of the day, move any unfinished tasks to tomorrow's list of six. Repeat.
Schwab reportedly paid Lee $25,000 for this advice — the equivalent of several hundred thousand dollars today. The reason it was worth that much is that it imposes a constraint most of us resist: you can only have six tasks. Not twelve. Not twenty. Six.
This forces you to make hard choices about what actually matters. It also eliminates the paralysis of a long list, because you always know exactly what to work on next — whatever is at the top. I don't follow it religiously, but on days when my list starts sprawling out of control, the Ivy Lee discipline of cutting it back to six is one of the best resets I know.
The 2-Minute Rule
David Allen, in his book Getting Things Done, introduced a principle that sounds minor but quietly transforms how you handle small tasks: if something takes less than two minutes, do it immediately. Don't write it down. Don't schedule it. Don't add it to any list. Just do it.
The reasoning is that the overhead of capturing, organizing, and later retrieving a tiny task costs more time and mental energy than simply executing it on the spot. Replying to a short email, filing a document, signing a form, making a quick phone call — these take less time to do than to manage.
I've found this particularly useful for preventing list bloat. Without the 2-minute rule, small tasks accumulate on the list and create a false sense of overwhelm. The list looks enormous, but half of it is trivial. Clearing those immediately keeps the list lean and focused on work that actually requires planning and sustained attention.
Time Blocking
Time blocking is the practice of assigning specific blocks of your day to specific types of work, rather than working reactively from a list.
The difference is subtle but significant. A to-do list tells you what needs to be done. Time blocking tells you when you'll do it. Without the second piece, the list is just a wish — a collection of intentions with no commitment to execution.
I schedule my most demanding cognitive work — writing, planning, analysis — for the hours when I know my focus is sharpest, typically mornings and late evenings. Administrative tasks, emails, and routine paperwork fill the gaps. This isn't rigid; the schedule adapts to the realities of the day. But having a default structure means I'm not constantly deciding what to do next. The decision is already made. I just follow the block.
Time blocking also makes you honest about capacity. When you assign tasks to actual hours, you quickly discover that your ambitious fifteen-item to-do list doesn't fit into the available time. That forces you to cut, delegate, or defer — which is exactly the kind of editing most to-do lists desperately need.
The Not-To-Do List
This is the twist that most people overlook, and it might be the most powerful tool of all.
A not-to-do list is exactly what it sounds like: a list of things you deliberately choose not to do. Habits, distractions, recurring time-wasters, low-value activities you keep defaulting to. Think of it as the bouncer at the door of your productivity — its job is to keep the wrong things out so the right things have room.
Start by observing, honestly, where your time actually goes when you're not being intentional. Social media during work hours. Unnecessary meetings you attend out of habit. Tasks you do because they're comfortable, not because they matter. Saying yes to requests that aren't aligned with your priorities.
Write them down. Put the list somewhere you'll see it. The not-to-do list doesn't require willpower in the moment — it requires a single act of honesty up front, and then it serves as a standing reminder of the boundaries you've set with yourself.
I've found this especially useful for protecting the time I've already blocked for important work. It's easy to plan a focused morning. It's harder to defend it against the dozen small intrusions that try to erode it. The not-to-do list is what holds the line.
Putting It All Together
None of these techniques work in isolation, and none of them need to be followed religiously. They're tools, and like any good toolkit, you pull out the one that fits the job.
My own daily practice looks something like this: I use the Ivy Lee method to cap my list at a manageable size. I apply Pareto thinking to identify which tasks will drive the most impact. I triage using the Eisenhower framework when the list feels chaotic. I eat the frog first, and if the frog is enormous, I cut it into elephant-sized bites. I clear anything under two minutes immediately. I block my time to make sure the plan has a home in the actual day. And I keep a not-to-do list to defend the whole system from the habits that would otherwise dismantle it.
Some days the system runs beautifully. Other days the Channel throws weather at the schedule and everything gets rearranged. That's fine. The point isn't perfection — it's having a framework that helps you make good decisions about where your time goes, even under pressure.
There is a good way to make a to-do list. Write things down, check them off, feel productive. But there is a better way: build a list that reflects your real priorities, respects your actual capacity, and adapts to the day as it unfolds. That's the list that moves the needle.
