(Excerpt from Rework by Jason Fried)
Another common misconception: You need to learn from your mistakes. What do you really learn from mistakes? You might learn what not to do again, but how valuable is that? You still don’t know what you should do next.
Contrast that with learning from your successes. Success gives you real ammunition. When something succeeds, you know what worked—and you can do it again. And the next time, you’ll probably do it even better.
Failure is not a prerequisite for success. A Harvard Business School study found already-successful entrepreneurs are far more likely to succeed again (the success rate for their future companies is 34 percent). But entrepreneurs whose companies failed the first time had almost the same follow-on success rate as people starting a company for the first time: just 23 percent. People who failed before have the same amount of success as people who have never tried at all.* Success is the experience that actually counts.
…Evolution doesn’t linger on past failures, it’s always building upon what worked. So should you.
