Entrepreneurship is about going for the things that are much bigger than what you could do alone. Your job isn't to reach the goal; it's to build a team that will reach the goal. If you really want to reach your goals, you'll need to bring on others to help, and creating a good executive team means knowing what you need them to do, finding good candidates, and giving them what they need to do their jobs. If you choose well, they'll be successful and make you successful as well.
