Ridiculous yachts and private planes and big limousines won't make people enjoy life more and it sends out terrible messages to the people who work for them. It would be so much better if that money was spent in Africa - and it's about getting a balance.
The greatest pleasure when I started making money was not buying cars or yachts but finding myself able to have as many freshly typed drafts as possible.
My friends are people who like building cool stuff. We always have this joke about people who want to just start companies without making something valuable. There's a lot of that in Silicon Valley.
