Choose someone who you think exemplifies excellence in some way.
Don’t worry about their faults. You’re not trying to become that person. You just want to learn a little more about how people become truly excellent in their field of performance.
As you study this person, search for their habits. Their habits will help you learn way more excellence than their natural gifts. What does, or what did, this person do consistently in order to become so good at what he or she does or did?
