Expect problems and eat them for breakfast.
Who seeks shall find.
If you're going through hell, keep going.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
But communication is two-sided - vital and profound communication makes demands also on those who are to receive it... demands in the sense of concentration, of genuine effort to receive what is being communicated.
