Making Money

In my Introduction to Entrepreneurship class we are working on developing our own business idea and will be pitching it to our classmates next week. When formulating a business idea and plan, one item that is stressed is the importance that this idea will be able to make revenues somehow. Consumers or investors of some kind will, in exchange for money, be able to consume the goods or services being offered. This seems like an obvious point but all the ideas I come up with are not so focused on consuming as they are sharing - sharing experiences, sharing resources etc. and I don't know how they will make money. I'd rather have my ideas generate positive ripple effects for people than profits necessarily, but unfortunately that is not how life works. Feeling frustrated with consumerism right now!
