Each day write down 1 thing you wish to accomplish for that day
It can be related to nutrition and fitness, it can be related to mental health, etc. Anything that will make you FEEL GOOD once you've completed it!
Keep a record of each day's achievements. Remember, it's 1 thing! 1 thing that will make you FEEL GREAT once you've accomplished it. Some days you can have repeats! Write it down, make it happen, and you've WON BY 1.
