You know, some people like to be regarded as being an analyst. They think that’s a term of endearment. I treat it as a personal insult if somebody calls me an analyst. A personal insult.If you’ve read the last paragraph, I’ve showed there are two things you have to be ableto do: analyze and synthesize. Analysis and synthesis. And if you can do that in many different areas, tactics, strategies, goals, unifying theme, you can run businesses, you can do any goddamn thing you want. And so when a person calls you an analyst, you’re really only a half-wit. You only got half. Idiot. So there’s two things that I don’t like being called, one an analyst, and the other is an expert. Because an expert means he knows everything and can’t learn anything new.He’s rigid.And boy, if you’re an analytical expert, you’re really in deep trouble.
