It's always too early to quit.
Well done is better than well said.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.
Who seeks shall find.
Never complain and never explain.
What you do today can improve all your tomorrows.
Know or listen to those who know.
Leap, and the net will appear.
Always desire to learn something useful.
When we are afraid we ought not to occupy ourselves with endeavoring to prove that there is no danger, but in strengthening ourselves to go on in spite of the danger.
