Don't wait. The time will never be just right.

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

The only way to do great work is to love what you do.In the midst of winter, I found there was, within me, an invincible summer.Your limitation—it’s only your imagination.

Keep your face always toward the sunshine, and shadows will fall behind you.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.

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.

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