That makes a lot of sense. It is incredibly important to sell what people need. The key to success in business is to find a perfect match - not only unfulfilled need. The good news is that it's really not that difficult to find that match when you know what you really want.
Many people assume that it is money they really want.
When you know what you love, you can also decide whom you WANT to serve. Probably those who share your values - it really is a lot of fun to do business with people you truly love. Much more fun than serving people only because they pay you. Of course, this kind of business is not easy to launch. Every single passion can be translated into a money-making business.
