Pain is temporary. It may last for a minute, or an hour or a day, or even a year. But eventually, it will subside. And something else takes its place. If I quit, however, it will last forever.
Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan Press On! has solved and always will solve the problems of the human race.
It does not matter how slowly you go, so long as you do not stop.
Success seems to be connected with action. Successful people keep moving. They make mistakes, but they don’t quit.
Hard work beats talent when talent doesn’t work hard.
When everything seems to be going against you, remember that the airplane takes off against the wind, not with it.
