I was once used to bullet journal, then I overthought about it and don't use it anymore.

I stick to a TODO list, but then I don't get this nice history and notes and so on. Maybe I will start a bullet journal over with these 5 symbols:
* for new task
x for a completed task

for a carried forward task
strikethrough is a cancelled task
- represents a note

No self-help-productivity-bullshit-post is complete without a list of tips, so here it is:

• Make it your own. Don’t attempt to shoehorn someone else’s solution.
• Don’t try to manage everything—that hardly ever works.
• Don’t over optimize. Task states don’t need 20 different symbols. Keep it simple.
• It doesn’t have to be an art project2. I know mine isn’t. Keep it functional.
