Well done is better than well said.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
Problems are not stop signs, they are guidelines.
I can, therefore I am.
Be gentle to all and stern with yourself.
Who seeks shall find.
You never know what motivates you.
Always desire to learn something useful.
Be thine own palace, or the world's thy jail.
Have convictions. Be friendly. Stick to your beliefs as they stick to theirs. Work as hard as they do.
My experience has been that work is almost the best way to pull oneself out of the depths.
