We tend to imitate the habits of three social groups: the close (family and friends), the many (the tribe), and the powerful (those with status and prestige). One of the most effective things you can do to build better habits is to join a culture where (1) your desired behavior is the normal behavior and (2) you already have something in common with the group.
Start now. Optimize later.
An imperfect start can always be improved, but obsessing over a perfect plan will never take you anywhere on its own.
Successful outcomes are never the result of a single choice. They are built up through good choices over time.
A profitable business is never a choice, it is a series of choices.
A fit body is never a choice, it is a series of choices.
A strong relationship is never a choice, it is a series of choices.
