Push yourself, because no one else is going to do it for you.

Great things never come from comfort zones.Don't wait. The time will never be just right.

Your limitation—it’s only your imagination.Your limitation—it’s only your imagination.Your limitation—it’s only your imagination.

You don’t have to be great to start, but you have to start to be great.The only way to do great work is to love what you do.

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

The key to success is to focus on goals, not obstacles.It’s going to be hard, but hard does not mean impossible.

Don’t stop when you’re tired. Stop when you’re done.Push yourself, because no one else is going to do it for you.

Your limitation—it’s only your imagination.In the midst of winter, I found there was, within me, an invincible summer.
