I write a list on word and at the end of the day I review my list.. I highlight things in green if completed, move things I was unable to complete to the next day and highlight things that I could have done, but slacked off in in red.
I also write a short paragraph recapping how things went.. things I was happy with, things I wasn't, what I want to get done the next day..
This is good because it holds me accountable, green highlighting feels good, red highlighting doesn't so its a habit that sustains itself quite well if I follow it.. Although sometimes (like right now) I stray from it slightly and don't do it every day..
I notice a definite difference in my days productivity and how I feel in general when I do and don't adhere to this system.
Would definitely recommend it
