To know oneself, one should assert oneself.
Always desire to learn something useful.
If you think you can do it, you can.
The most effective way to do it, is to do it.
Know or listen to those who know.
Well done is better than well said.
You never know what motivates you.
Never complain and never explain.
Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
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.
