What habit did you pick up recently that improved your life in a notable way?

Getting (late to the party I might add) Whoop, have definitely seen a difference in my sleeps etc and I pay a lot more attention to physical health with it.

Same for me - some cardio and light weights at home for 30-60min a day did wonders! I think everyone who works out sees an overall improvement. Exercising makes you commit to it, and this habit often translates to other areas in your life (personal, professional etc)
