Never complain and never explain.
Always desire to learn something useful.
If you can dream it, you can do it.
Leap, and the net will appear.
Know or listen to those who know.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
He who devotes sixteen hours a day to hard study may become at sixty as wise as he thought himself at twenty.
