Problems are not stop signs, they are guidelines.
Never complain and never explain.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Well done is better than well said.
If you're going through hell, keep going.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
Know or listen to those who know.
Always desire to learn something useful.
Learned men are the cisterns of knowledge, not the fountainheads.
