Soros is definitely weird at times, and he is almost always too-certain. But your negative characterization of "billionaire investor" is a disservice to you and him. Rather than learn about the world by selling products or climbing a political ladder, he formed opinions and made bets. Massive, massive respect.
If we throw out, even if momentarily, that there's more to success in the markets than pure luck, then people who have succeeded have done so in a very pure way: you can only make money in trading by being right. When you're right as often and to the extent that someone like Soros is, you have insight that 99.9999% of people don't.
