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

It’s going to be hard, but hard does not mean impossible.Success is not final, failure is not fatal: It is the courage to continue that counts.

Push yourself, because no one else is going to do it for you.Don't wait. The time will never be just right.You don’t have to be great to start, but you have to start to be great.

It’s going to be hard, but hard does not mean impossible.The key to success is to focus on goals, not obstacles.

The only way to do great work is to love what you do.

Keep your face always toward the sunshine, and shadows will fall behind you.The only way to do great work is to love what you do.

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

It’s going to be hard, but hard does not mean impossible.Don’t stop when you’re tired. Stop when you’re done.
