The key to success is to focus on goals, not obstacles.

Don’t stop when you’re tired. Stop when you’re done.Push yourself, because no one else is going to do it for you.

Success is not final, failure is not fatal: It is the courage to continue that counts.Success is not final, failure is not fatal: It is the courage to continue that counts.Don't wait. The time will never be just right.

The harder you work for something, the greater you’ll feel when you achieve it.Keep your face always toward the sunshine, and shadows will fall behind you.

Your limitation—it’s only your imagination.

Push yourself, because no one else is going to do it for you.Great things never come from comfort zones.

The way to get started is to quit talking and begin doing.Success is not final, failure is not fatal: It is the courage to continue that counts.

Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.In the midst of winter, I found there was, within me, an invincible summer.
