There are shelves full of business books that offer intricate case studies, anonymized anecdotes, and bromides based on academic research. What makes this advice from FUBU founder Daymond John  so valuable is that every bit of it is based on his own experience. And the lessons can be applied not just to fashion businesses, but to plenty of other startups, too. Who is your customer? What's your price point? Start local. Don't sell out too early. And this bit of advice, which John learned from his own mentor:
"OPM should not be other people's money. It should be other people's mind power, other people's manufacturing, other people's marketing, and a lot of times you can profit from other people's mistakes."
