Courage is very important. Like a muscle, it is strengthened by use.
Try something new each day. After all, we're given life to find it out. It doesn't last forever.
I think there is one smashing rule: never face the facts.
If you believe, then you hang on. If you believe, it means you've got imagination, you don't need stuff thrown out on a blueprint, and don't face facts-what can stop you? If I don't make it today, I'll come in tomorrow.
My body is on the earth, but my head is in the stars.
Get up early in the morning before everybody has breathed up all the good air.
