I'm interested to hear your methods, tools, and philosophies. Do you write meticulous to-do lists? Pen-n-paper, or a favourite app? Rigorous habit building?

Whatever it is you do that keeps your life in check and gets you to do things on time, I'd love to hear it.

I was wondering if anyone organizes their life in checklists, and if so, how people go about doing it. I'm interested in starting to try this, but haven't yet taken the time to do so and I'm curious what works for people.
My idea of this came off of CGP Grey's usage, which he often talked about in his podcast with Brady Haran, Hello Internet, but I'm a Windows/Android kind of person and would probably use a program such as Notion, which I'm using for notetaking and other tasks already, to do so.

What I'm mainly wondering is how you might structure checklists to a day of the week, and what to include/not include on there. What works for you if you've tried this before, and would you recommend it?
