Everyone is an entrepreneur. We all sell something to someone and get something from that person in return.
Whatever you do for a living and no matter who you think your boss is, you are actually your own business. Even if you’re living the corporate American dream, you sell something (your time) for a price (your salary) to your customer (your employer).
The question is, do you have a good business model? Is what you get in return for your time a fair price? Would you actually be better off selling your time to someone else . . . or selling less of it so that you have more to spare for your own use?
