Expect problems and eat them for breakfast.
It's always too early to quit.
Wherever you are - be all there.
Quality is not an act, it is a habit.
Never complain and never explain.
After a storm comes a calm.
I can, therefore I am.
If you think you can do it, you can.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.
