If you've got a talent, protect it.
It's always too early to quit.
Expect problems and eat them for breakfast.
Know or listen to those who know.
Always desire to learn something useful.
Only the educated are free.
Wherever you are - be all there.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.
