If you never have a single great idea in your life, but become skilled in executing the great ideas of others, you can succeed beyond your wildest dreams. Seek them out and make them work. They do not have to be your ideas. Execution is all in this regard. If, on the other hand, you spend your days thinking up and developing in your mind this great idea or that, you are unlikely to get rich. Although you are likely to make many others rich. That is usually the way of it. Ideas don’t make you rich. The correct execution of ideas does.
