The brain is a complex entity, full of tricks and loops. We each seem to like to think “I control me”, but this is a simplistic view. Our motivation stems a great deal from the environment we accept.
In other words, we give each other structure. Place yourself in a structure that demands high-quality behavior, and it’s naturally easier to overcome laziness.
The journey to success is then dependant on spending time discovering where that structure exists and seeking it out.
Colonize the unknown and make it yours.
