Never complain and never explain.
If you can dream it, you can do it.
Either you run the day or the day runs you.
Do not weep do not wax indignant. Understand.
It's always too early to quit.
You never know what motivates you.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Who seeks shall find.
Be gentle to all and stern with yourself.
