It's not about how hard you hit. It's about how hard you can get hit and keep moving forward.
The only person you should try to be better than is the person you were yesterday.
Strive not to be a success, but rather to be of value.
The only limit to our realization of tomorrow will be our doubts of today.
In every adversity lies the seed of an equal or greater opportunity.
Your time is limited, so don't waste it living someone else's life.
