When my bed was tidy, I wanted the rest of the room to match it, so everything else was kept cleaner. Also, after making my bed, I felt like I was more on top of my sh*t — which prompted me to remember to take my probiotic, get the dog out for a brisk, fresh 30-minute walk (great for me, too!), and eat something healthy before tackling the day's challenges.
It's a common adage that one good choice begets another, and it's really true. I learned this extensively through that book I read (The Power of Habit — highly recommend TBH) and learned it IRL when I tried it myself. Starting small with one task like making the bed allowed me to have that sense of victory, which in a funny way was an empowering self-esteem boost that I channelled into even more good habits.
