“You need three things to become a successful novelist: talent, luck and discipline. Discipline is the one element of those three things that you can control, and so that is the one that you have to focus on controlling, and you just have to hope and trust in the other two.”

“My definition of Blues is that it's a musical form which is very disciplined and structured coupled with a state of mind, and you can have either of those things but it's the two together that make it what it is. And you need to be a student for one, and a human being for the other, but those things alone don't do it.”

“I have two maxims that I believe, dear girl. One, if you can control yourself, you can control others. Two, if you can control information, you can control others.”

“You only have control over three things in your life-the thoughts you think, the images you visualise, & the actions you take.”

“You cannot be disciplined in great things and undisciplined in small things. Brave undisciplined men have no chance against the discipline and valour of other men. Have you seen a few policemen handle a crowd?”

“Acting with discipline requires you to know your true nature and, having come to know it, to bring it under control.”
