Learning is underrated. I'll be the first to tell you that I'm always learning on the fly, because that's always the best way to learn. Most people always try to act like they know it all, but no one really knows much. In fact, the irony is that the more someone thinks he knows everything, the less he actually knows. That's because his attitude prevents him from learning more.
One of the keys to being successful in this world is actually realizing how little you know, and using that to motivate you to learn more. That's a very valuable lesson to anyone, not just entrepreneurs, inventors, or worker bees.
And against a common misconception, you don't have to have an IQ of 160 to be successful. Unlike the classroom, an "E" for effort in the business world is better than an "A+". You just have to be willing to spend the time educating yourself, learning, testing, retesting, failing, and then succeeding. There is always too much to learn, so grab a hold of something you enjoy, keep digging . . . and don't stop. If you need an inspirational movie to get your started, go see the Pursuit of Happiness.
