Ego is the enemy. Repeat those four words every day.
Ego defeats people every day. It is the case of conflicts and disagreements. It leads smart men to make dumb decisions. Think how poorly dumb men fare against its might. It can never be defeated or conquered, only temporarily subdued.
Before every decision, ask yourself, “How is my ego influencing my decision here?”
And remember to thank Ryan Holiday for writing a great book on the subject.
P.S. I've committed to getting a tattoo similar to Holiday when we do 'make it'.
