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

The key to success is to focus on goals, not obstacles.The way to get started is to quit talking and begin doing.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.Keep your face always toward the sunshine, and shadows will fall behind you.

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

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

The only way to do great work is to love what you do.Believe you can and you're halfway there.

Great things never come from comfort zones.You don’t have to be great to start, but you have to start to be great.
