Through discipline, and determination one can change anything and everything about him - his habits, his outlook on life

The mind is incredible. Once you've gained mastery over it, channeling its powers positively for your purposes, you can do anything. I mean anything. The secret is to make your mind work for you not against you. This means constantly being positive. Constantly setting up challenges you can meet either today, next week, or next month. "I can't..." should be permanently stricken from your vocabulary, especially the vocabulary of your thoughts. You must see yourself always growing and improving.

For me life is continuously being hungry. The meaning of life is not simply to exist, to survive, but to move ahead, to go up, to achieve, to conquer.

Having chicks around is the kind of thing that breaks up the intense training. It gives you relief, and then afterward you go back to the serious stuff.

I don't walk away from things that I think are unfinished.

I have a private plane. But I fly commercial when I go to environmental conferences.

People who say "it is impossible", should not interrupt those who are trying to make it possible.
