Ask HN: What routines do you recommend that you've stuck with for 6+ months?

Routines and the systems that support them/rely on them are often touted as a major contributor to success. Even though everyone has an opinion, people either have just implemented something and it suffers from the newness fallacy and/or people just want to share everything they are doing. I'm hoping to get an idea of what has stood the test of time that works specifically for you.
