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

The key to success is to focus on goals, not obstacles.Success is not final, failure is not fatal: It is the courage to continue that counts.

Your limitation—it’s only your imagination.The harder you work for something, the greater you’ll feel when you achieve it.The greatest glory in living lies not in never falling, but in rising every time we fall.

Keep your face always toward the sunshine, and shadows will fall behind you.You don’t have to be great to start, but you have to start to be great.

Success is not final, failure is not fatal: It is the courage to continue that counts.

Believe you can and you're halfway there.The harder you work for something, the greater you’ll feel when you achieve it.

Believe you can and you're halfway there.Push yourself, because no one else is going to do it for you.

Keep your face always toward the sunshine, and shadows will fall behind you.The way to get started is to quit talking and begin doing.
