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

The harder you work for something, the greater you’ll feel when you achieve it.The only way to do great work is to love what you do.

Great things never come from comfort zones.Don’t stop when you’re tired. Stop when you’re done.Dream it. Wish it. Do it.

It’s going to be hard, but hard does not mean impossible.Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

Don't wait. The time will never be just right.

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.

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

Don’t stop when you’re tired. Stop when you’re done.In the midst of winter, I found there was, within me, an invincible summer.
