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

The harder you work for something, the greater you’ll feel when you achieve it.Your limitation—it’s only your imagination.

Don't wait. The time will never be just right.Don't wait. The time will never be just right.The only way to do great work is to love what you do.

The key to success is to focus on goals, not obstacles.Don’t stop when you’re tired. Stop when you’re done.

Don’t stop when you’re tired. Stop when you’re done.

Wake up with determination. Go to bed with satisfaction.You don’t have to be great to start, but you have to start to be great.

Wake up with determination. Go to bed with satisfaction.Keep your face always toward the sunshine, and shadows will fall behind you.

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