Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
You never know what motivates you.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
Never complain and never explain.
What you do today can improve all your tomorrows.
Most of man's problems upon this planet, in the long history of the race, have been met and solved either partially or as a whole by experiment based on common sense and carried out with courage.
