It's always too early to quit.
The most effective way to do it, is to do it.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
I can, therefore I am.
The secret of getting ahead is getting started.
Never complain and never explain.
To be a good loser is to learn how to win.
I carry groceries home on the tank of my motorcycle.
