"Every saint has a past, and every sinner has a future."
A leader does not deserve the name unless he is willing occasionally to stand alone.
Your work is going to fill a large part of your life, so make sure it's something you love doing.
We're not going to run out of ammunition.
We must eradicate from the soul all fear and terror of what comes towards us out of the future.
Change is hard, but it is necessary for progress.
