Personally, I've been very unlucky in business. If you asked me if there was a catapult for my success, I would say there was none, though I tried to build multiple, and still do. They all failed, because like I said, I'm perpetually unlucky. But I've been very determined -- hardheaded, even -- and after nearly 10 years, I'm quite successful. Not quite above 7 figures yet, but that's really just a function of time -- and determination, of course.
Sometimes you may even feel unskilled simply because you feel unlucky, but time has usually shown that to be a false assumption. Waiting on luck would've made me give up a long time ago, while skill with relentlessness determination has paid off for me.
However, a hunger is not enough. You do need some skill, or at least some luck.
