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

Don’t stop when you’re tired. Stop when you’re done.Keep your face always toward the sunshine, and shadows will fall behind you.

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.In the midst of winter, I found there was, within me, an invincible summer.

Do something today that your future self will thank you for.Wake up with determination. Go to bed with satisfaction.

You don’t have to be great to start, but you have to start to be great.

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

Do something today that your future self will thank you for.The only way to do great work is to love what you do.

Push yourself, because no one else is going to do it for you.In the midst of winter, I found there was, within me, an invincible summer.
