The reason why you should write down everything you have to do (except for the exceptions)


Datum: 2025-08-26 08:09
A young woman with long hair and glasses is puffing out her cheeks and looking up thoughtfully, standing against a bright orange background.

I had just spo­ken enthu­si­as­ti­cal­ly about the immense val­ue of choos­ing only one tool to keep your entire to-do list in at the full-day course in struc­ture I held at a big hos­pi­tal when one of the par­tic­i­pants raised his hand and said: Do you real­ly have to write to every­thing you have to do? Can’t I just con­tin­ue to keep all the things I keep in my head there instead of on paper somewhere?”.

The ques­tion is valid since it does in fact take longer to write down a task than to not write it down. And being struc­tured and orga­nized is not an end in itself, but a means to an end and only use­ful if it actu­al­ly helps us. 

If you have things you usu­al­ly do and which you, there­fore, are com­plete­ly sure you will remem­ber to do, you do not need to write them down just because. 


For you who prefer listening to reading, this post is also available as an episode of the ""Done!"" podcast:


Four ben­e­fits of keep­ing a list

But, as I see it, there are four good rea­sons why I write down every­thing I have to do:

  1. When I am about to choose what to do next, I want to do so based on accu­rate pri­or­i­ti­za­tion. To do this, it is much eas­i­er if I can see all the things I could poten­tial­ly do in one sin­gle place, in a list, rather than rack my brain (or worse, part of my brain) for what I have to do. If I choose my next task from those float­ing around in my mind, I tend to either choose the tasks that stress me the most and which I, there­fore, want to get rid of as soon as pos­si­ble or the tasks that feel either most exten­sive or urgent. The point is, these might not be the right tasks to do right now.
  2. If I just keep tasks in my head I risk miss­ing things that need to get done today and which I promised some­one else I would do quite some time ago and, there­fore, do not have fresh in mind.
  3. I want to ded­i­cate my capac­i­ty to oth­er, more inter­est­ing, and pro­duc­tive thoughts than think­ing Oh yeah, I almost for­got! I have to remem­ber to do that lat­er.” over and over again.
  4. I have for­got­ten to do things because I only com­mit­ted them to mem­o­ry. It was not pleas­ant at all and I do not want to repeat the experience…

If you agree with me on all four points above, then write down all the things you will not do imme­di­ate­ly. Go ahead and keep the things you are cer­tain you will do any­ways in your head, as well as the things you do because you enjoy them, but keep every­thing else that you must not for­get to do some­place oth­er than in your head.

Do this

Take a few moments right now to recall if there is any­thing you car­ry around” in your mind which you can­not for­get to do but which is not on your to-do list (or sim­i­lar tool that you use).

If you real­ize that you have some­thing float­ing around in there that is not on your list, write it down instead. Your list will become more of an actu­al­ly com­pre­hen­sive overview of all the things you have to do and your can use your mind to do more inter­est­ing things than keep­ing track of your to-dos.

Free up your mind for oth­er things

If you make sure to write down all the things you have to do, it will become eas­i­er to do more of what you want and have promised oth­ers to do. Only put things that you might oth­er­wise for­get on your list, and skip the things you know for sure you will do any­ways — remem­ber, the list is not an end in itself; it is a tool and a means to you get­ting the right things done. If you abide by these sim­ple guide­lines, you will find that struc­ture helps you rather than being a bor­ing must.

What’s your way?

Do you still find your­self keep­ing things in your head? What kinds of things? In what way is it bet­ter for you to keep it all in your mind than on a list? Please write and share your thoughts. 

I want to know what it is like for you, what helps you, and what doesn’t. Per­son­al­ly, I love hav­ing my mind free from all the have to’s” and would rather keep those on a list some­where, but we are all different.
