As we grow into adulthood, we have to learn a multitude of lessons in order to be successful, well-adjusted human beings. Don’t hit your big brother or he’ll probably slug you back harder. Check. Don’t eat an entire cake for dinner or you’ll probably have a stomachache. Check. Look before you cross the street or you’ll probably get hit by a car. Check. Our lessons obviously mature as we mature, but if we’re smart, we never stop learning. We probably learn thousands of lessons in our lifetime -- and if you’re an entrepreneur, you can go ahead and double that number.
