Great things never come from comfort zones.

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

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

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.

Your limitation—it’s only your imagination.

Believe you can and you're halfway there.The key to success is to focus on goals, not obstacles.

Wake up with determination. Go to bed with satisfaction.The harder you work for something, the greater you’ll feel when you achieve it.

Don't wait. The time will never be just right.Keep your face always toward the sunshine, and shadows will fall behind you.
