Hello there~ One of my personal favourites is:
“Anything worth doing is worth doing poorly, because doing it poorly is better than not doing it at all.”
(The explanation for this is brushing your teeth for 30 seconds is better than not brushing them at all when that 2 minutes seems exhausting. Doing ten minutes of yoga is better than 10 minutes of sitting when 30 minutes of cardio sounds impossible. Changing my clothes is good when a whole shower is impossible. Standing on the porch for a few minutes is worth it after being in the house for three straight days because I don't have the energy to go anywhere.)
Yours doesn’t have to explain or be as long as mine.
Sorry, found the thread for this that everyone else is using. I'm not sure why there are 2.
