Our heritage and ideals, our code and standards - the things we live by and teach our children - are preserved or diminished by how freely we exchange ideas and feelings.

It is no use saying, 'We are doing our best.' You have got to succeed in doing what is necessary. 

To be successful, you have to have your heart in your business and your business in your heart. 

The future rewards those who press on. I don't have time to feel sorry for myself. I don't have time to complain. I'm going to press on.

Innovation distinguishes between a leader and a follower.

When you smoke the herb, it reveals you to yourself.

The energy of the mind is the essence of life.

The difference between what we do and what we are capable of doing would suffice to solve most of the world's problems.

I want to be just a pure spiritual leader.

Many interviewers when they come to talk to me, think they're being progressive by not mentioning in their stories any longer that I'm black. I tell them, 'Don't stop now. If I shot somebody you'd mention it.'

Although personally I am quite content with existing explosives, I feel we must not stand in the path of improvement. 

In a consecrated calm, forgotten yet. Of the keen heart that hastens to forget old longings in fulfilling new desires.
