Don’t stop when you’re tired. Stop when you’re done.

The key to success is to focus on goals, not obstacles.Don't wait. The time will never be just right.

Success is not final, failure is not fatal: It is the courage to continue that counts.Believe you can and you're halfway there.You don’t have to be great to start, but you have to start to be great.

Keep your face always toward the sunshine, and shadows will fall behind you.In the midst of winter, I found there was, within me, an invincible summer.

It’s going to be hard, but hard does not mean impossible.

You don’t have to be great to start, but you have to start to be great.Your limitation—it’s only your imagination.

The key to success is to focus on goals, not obstacles.Don’t stop when you’re tired. Stop when you’re done.

Your limitation—it’s only your imagination.Believe you can and you're halfway there.
