In the midst of winter, I found there was, within me, an invincible summer.
It’s going to be hard, but hard does not mean impossible.
The key to success is to focus on goals, not obstacles.
The only way to do great work is to love what you do. 
Wake up with determination. Go to bed with satisfaction.
