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.Great things never come from comfort zones.

The key to success is to focus on goals, not obstacles.It’s going to be hard, but hard does not mean impossible.Your limitation—it’s only your imagination.

Push yourself, because no one else is going to do it for you.It’s going to be hard, but hard does not mean impossible.

Great things never come from comfort zones.

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

The harder you work for something, the greater you’ll feel when you achieve it.Keep your face always toward the sunshine, and shadows will fall behind you.

Your limitation—it’s only your imagination.Don't wait. The time will never be just right.
