Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
If you think you can do it, you can.
It's always too early to quit.
Do not weep do not wax indignant. Understand.
Either you run the day or the day runs you.
Well done is better than well said.
The most effective way to do it, is to do it.
If you're going through hell, keep going.
You never know what motivates you.
The nice thing about being a writer is that you can make magic happen without learning tricks.
