I don't keep todo lists.

Todo lists are for assistants and entry level engineers grinding away at bugs.

(not to be disrespectful to those people, just trying to get my point across).

Senior staff focuses on vision and long term goals of the company, which are mostly emotional and in your head anyways.

And things like „fix broken bike bell“ - if it‘s important enough, it will come up often enough to bug me and I will get it fixed.

Just make sure not to outsource reminders in other people, ie don‘t rely on people having to remind you several times before you actually do something.

Delegate the task away right away, or reject it, or become passionate enough about it to not need a todo list.
