Be gentle to all and stern with yourself.
If you've got a talent, protect it.
Know or listen to those who know.
It's always too early to quit.
Only the educated are free.
To know oneself, one should assert oneself.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
