I guess this thread is dead, but I'm just replying again because it showed-up in my 'Subscriptions' section. Another pretty valid reason for trading OPM is credibility - not only to family and friends (and if someone thinks that shouldn't matter then they're just a young, stupid kid), but to banks and anyone else you might want to take you seriously. A bank won't give you a loan for that beach house or Ferrari if you don't 'get paid' somehow (with OPM) - and to that end, eventually starting an LLC (I'm assuming you're in the US) will give you a paycheck.
