I made a notebook which I keep on my nightstand and each night I reflect on what I am calling my 5 P's.
Peak - High Point
Pit - Low Point
Praise - What I am thankful for that day
Prospect - What I am looking forward to tomorrow
Prayer - Prayer of the day
It's never much. I don't write pages, just a phrase or so for each. I have really found this to be a beneficial practice and I would highly recommend it! Feel free to steal it and use it!
