When I die and go to hell, the devil is going to make me the marketing director for a cola company. I’ll be in charge of trying to sell a product that no one needs, is identical to its competition, and can’t be sold on its merits. I’d be competing head-on in the cola wars, on price, distribution, advertising, and promotion, which would indeed be hell for me. Remember, I’m the kid who couldn’t play competitive games. I’d much rather design and sell products so good and unique that they have no competition.

You can solo-climb Everest without using oxygen or you can pay guides and Sherpas to carry your loads, put ladders across crevasses, lay in 6,000 feet of fixed ropes, and have one Sherpa pulling you and another pushing you. ... The goal of climbing big, dangerous mountains should be to attain some sort of spiritual and personal growth, but this won't happen if you compromise away the entire process.

Evil doesn’t have to be an overt act; it can be merely the absence of good. If you have the ability, the resources, and the opportunity to do good and you do nothing, that can be evil.
