I have a checklist that I use throughout the day, every single day. It slowly evolves as I delete items that are automatic or aren't helpful, I add and change things I want to become new habits.

The sections:

GENERAL - One or two things to remember through the day, for building new habits
START OF DAY - My morning routine, to ideally be done every morning, or at least tracked
MOST KEY ITEM - My biggest one or two things for the day. I evaluate whether a day is successful or not by whether I do one most key item
PEOPLE - More and more, I realize most important and meaningful things need to be done with people.
GENERAL - Funny that I named two sections General, hadn't realized until now. This is thinking about my life goals, cash has been added recently for tracking.
END OF DAY - A review of the day and some thoughts on the next day. Also, I add what time I went to sleep.
