Always desire to learn something useful.
After a storm comes a calm.
It's always too early to quit.
Wherever you are - be all there.
Without hard work, nothing grows but weeds.
Never complain and never explain.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
But to me the bottom line is the more education you can give yourself, and the more preparation you can do, the less chance of failing.
