90% of willpower is preparation. Arrange your life to make the things you should do easier and the things you should avoid less convenient.
Example: To avoid sleeping in, or worse, dicking around on my phone instead of sleeping or getting up, I put my phone to charge on the other side of the bedroom.
Another: I put a speaker in my kitchen to listen to music when I wash dishes. A lot easier to wash just those last few pots, even if I feel like I’m ready for a break, if I want to finish the song.
