Remember that a good example is the best sermon.
Your mind can only hold one thought at a time. Make it a positive and constructive one.
Love your work, then you will find pleasure in mastering it.
Talent without discipline is like an octopus on roller skates. There's plenty of movement, but you never know if it's going to be forward, backwards, or sideways.
Never be ashamed of your patriotism.
Never deprive someone of hope; it might be all they have.
