It's always too early to quit.
Do not weep do not wax indignant. Understand.
If you can dream it, you can do it.
Always desire to learn something useful.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
You never know what motivates you.
He who devotes sixteen hours a day to hard study may become at sixty as wise as he thought himself at twenty.
