I moved cross-country with about $800 to my name and I've made over $600,000 since.
Of course, it was pretty tough for the first few years, grinding out 12-14 hour days and making $15,000-$20,000 a year. It wasn't much, but enough to live on, and I was gathering valuable experience. After I felt like I had built up a good knowledge base, I moved up to the big leagues. The stakes were a lot higher - instead of thousands of dollars, we're talking millions of dollars here, and perhaps even billions. Teamwork, as always, is essential in these sort of matters, as is having strong financial backers who can ride through a rough patch. It's pretty embarrassing to say that you took a $10,000 gamble that didn't yield anything at all, but they have to understand that it was a shot worth taking, and that sooner or later one of those $10,000 shots is going to pay off 10,000:1.
Oh, wait, you were talking about blackjack ... never mind.
