Something on your “to-do list” that never gets done.
To do it lists help us organize our thoughts, prioritize our tasks, and reduce cutter and provide a sense of accomplishment by visually displaying what needs to be done and allowing us to check off completed items. Which leads to increased productivity and better time management. 
I try not to make long daily to do it lists. Otherwise, I feel like unaccomplished. If I can get three or four things on my do it list today then. I feel good, but putting 10 things on my to do list I get overwhelmed and overthink, feeling like I have to rush through things. The rushing is what gets me in trouble.
