To-do list is one of the more common tools in the arsenal of someone trying to stay on top of things. The idea is very simple, you write down a list of things that you need to do, be it in an app on your phone or on a piece of paper, and keep checking them off one by one. The part of checking off things from your list is indeed very satisfying. Personally for me too, I have found that I am much more likely to do a task if I write it in my to-do list AND I actually refer back to the list frequently. While to-do lists are helpful, they also have a bad reputation of being overwhelming and making you feel that you are not doing enough.
