Change is not difficult. The easiest thing to do in the world is to change. Sustaining change is what's difficult. But I had to start, I had to walk before I could jog, before I could run, before I could run races, before I could run marathons. It was Calvin Coolidge who said, Nothing in the world can take the place of persistence.
Unrewarded genius is almost a proverb.
Talent alone will not. Nothing is more common in this world than unsuccessful people with talent. Education alone will not. The world is full of educated derelicts. Persistence, determination alone, are omnipotent.
