In 2001 and 2002 I lost all my money through bad investing. The same thing happened to me on a couple of occasions after that.
So why should anyone listen to me about investing? You shouldn't. You shouldn't listen to anyone at all about investing. This is your hard-earned money. Don't blow it by listening to an idiot like me.
Here's my experience (and perhaps I've learned the hard way about what NOT to do and a little bit about what TO do.):
I've run a hedge fund that was successful. I ran a fund of hedge funds, which means I've probably analyzed the track records and strategies of about 1000 different hedge funds.
