Motivation can't take you very far if you don't have the legs.
Make an obstacle an opportunity, make a negative a positive.
I'm sorry you don't believe in miracles.
I've committed to surfing the rest of my life.
I have never had a single positive doping test, and I do not take performance-enhancing drugs.
Do it even if you shouldn't, do it becuase you want to, do it becuase it will make things better.
