The mind is just another muscle.

I don't measure success in numbers, but I consider my contributions of more than $1.3 billion to various causes over the years to be one of my proudest accomplishments and the best investment I've ever made. Those dollars have improved lives, saved species, fought disease, educated children, inspired change, challenged ideas and opened minds; at the time of my death, virtually all of my wealth will have gone to charity.

Over-population is the 'cause of drive-by shootings' and other social ills, but the root of the problem is Christianity, which posits that people are more important than sea otters and elephants.

A total population of 250-300 million people, a 95% decline from present levels, would be ideal.

Many times through the ages, like as not the chance appears, but because of indecision, man's fond hopes are drowned in tears.

I've had the good fortune to have a much more diverse life than most people would, professional sports and television and news and movies.

Every man sees a little of himself in Rhett Butler.
