I can, therefore I am.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
Expect problems and eat them for breakfast.
It's always too early to quit.
If you're going through hell, keep going.
The most effective way to do it, is to do it.
You never know what motivates you.
Don't write anything you can phone. Don't phone anything you can talk. Don't talk anything you can whisper. Don't whisper anything you can smile. Don't smile anything you can nod. Don't nod anything you can wink.
