Sometimes buying an already profitable website is easier than building one from scratch

What's a mistake you learned the hard way that you can now help people to avoid? Probably that sort of online entrepreneurship doesn't have to be riddled with failures getting from zero to one, and that anyone can buy an already profitable online business from anywhere from like $500 to $500,000 that makes you money on day one. And before you ask me where to go buy these businesses, go check out Flippa.com, Quietlight, FE International, MicroAcquire, and let me know in the comments if you want me to break down each one of them and which ones have the best deals.
