Great things never come from comfort zones.

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

In the midst of winter, I found there was, within me, an invincible summer.Don’t stop when you’re tired. Stop when you’re done.The harder you work for something, the greater you’ll feel when you achieve it.

Your limitation—it’s only your imagination.Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

Believe you can and you're halfway there.

The key to success is to focus on goals, not obstacles.Keep your face always toward the sunshine, and shadows will fall behind you.

Wake up with determination. Go to bed with satisfaction.The only way to do great work is to love what you do.

The key to success is to focus on goals, not obstacles.Push yourself, because no one else is going to do it for you.
