Humans are imitation machines. We mostly learn what to do by copying those around us.
In general, we imitate the habits of three groups:
1. The close - what are friends and family doing?
2. The many - what is the crowd doing?
3. The powerful - what are those with status doing?
"Most things are not as difficult as they seem—if you focus each day.
However, giving one topic your full attention for an extended period of time is even harder than it seems.
Over a long timeline, the bottleneck is usually attention not ability."
