Okay. There is no reasonably safe way to turn tens of thousands of dollars into hundreds of thousands in 2-3 years.<p>Was that tepid enough or should I also insert a series of sleep-inducing legal disclaimers? ;)<p>The above advice is utterly conventional. Every reputable book on investing says it. Indeed, most books and pamphlets on how to get rich quick say it as well, in the footnotes that nobody reads. The brain slides off such disclaimers like water off a duck.<p>So one tries to find a more dramatic way to say the same thing.<p>And while I'm explaining things I thought were obvious: The OP is not a gambler -- or, rather, he has placed an intelligent bet and <i>won</i>: He is now making money hand over fist by <i>building products that sell</i>. Nothing wrong with that. Except that now the OP seems to be having that unnerving feeling -- which everyone gets at least once in their lives -- that he's missing out on <i>something big</i>, some kind of <i>big secret to moneymaking</i> that the cognoscenti know. And, indeed, there are people who make amazing amounts of money in 2-3 years. They do it by gambling -- and when gambling works, it works. It just doesn't work very often, and you rarely hear from the people who place risky bets and fail. One's mind often fails to register those people. Sometimes you have to take deliberate, dramatic steps to make yourself see them.
