It takes nothing more than changing the way you see the world. The bad news is it will also require you to work hard and take action. As an entrepreneur you are always looking for and taking advantage of new angles and opportunities. Chances are those great ideas you have bouncing around your head have been thought of before, the question is, are you willing to take the chance and make something happen? Even if you don't end up making money the first time around you will build your understanding of what works and what doesn't. The trick is to get the fly wheel of experience going and come back to give it a push as often as you can.
If a great idea comes to you, evaluate if it is realistic. Think of cost, manufacturing time, and popularity.
Years later, the successful ideas are "obviously" good, but when they first began, most people rejected them. Google is one of the most famous examples - "Search is done. Does the world need yet another search engine?"- but many less-spectacular successes have strong arguments against them.
