The things is, whether I make this list or not, I will honestly get the same things done. Only, when I make the to-do-list, I get to physically take a pen at the end of the day and cross off the things I've already done. This makes me feel accomplished, and thus positive about my day. If I can see, with my very own eyes, that I've completed a task(s) that I set out to, then that makes it a good day.
I do this for writing, as well as my day-to-day life -- often with one list per day scribbled on post it on my kitchen counter and one scribbled on my desk. (That's two lists that I'm allowed to cross things off of at at the end of the day!)
Do you make to-do lists? Do they make you feel positive or negative about your day?
