Barack Obama on the importance of routine:
You need to remove from your life the day-to-day problems that absorb most people for meaningful parts of their day… You’ll see I wear only grey or blue suits. I’m trying to pare down decisions. I don’t want to make decisions about what I’m eating or wearing. Because I have too many other decisions to make. You need to focus your decision-making energy. You need to routinize yourself. You can’t be going through the day distracted by trivia. (Source: Vanity Fair)
This is great advice on how to ensure that we keep our focus on things that matter and reduce the level of stress in our lives. Much of stress in our lives derives from having to make countless small decisions about things that have minimal importance. These things should at best be routine to reduce inefficient use of time.
