A to-do list feels like one of those things that almost everyone on the planet has, be it an old school one handwritten in a paper notebook or some kind of app.

Personally, however, I don’t have any kind of conventional to-do list. Instead, for decades now, I’ve been in the habit of using a calendar as my to-do list, and here are the reasons you too might want to give this a try …

When it comes to task management and to-do lists, there are literally dozens of different systems out there. Getting Things Done, Bullet Journal, PARA, Eisenhower Matrix, Ivy Lee, Eat the Frog, MITs, MoSCoW, 1-3-5, Kanban … I could go on.

I’m a systems kind of guy: organizing stuff is basically a hobby to me. I could absolutely go down any of these rabbit holes and try organizing my life in any of those ways. Instead, however, I long ago came up with a simple yet highly effective approach which I’ve used ever since.

It happened after I’d been staring at a very lengthy set of categorized to-do lists and wondering when on earth I was actually going to be able to complete them. I decided the solution was to look at them in priority order, work out roughly how long each item was going to take, and then schedule each in my diary.
