Liked what you read? I am available for hire.
I have a car on campus and have started selling rides to the airport for fall break. Sure, I'm cheaper than a cab, but most people just find someone to give them a ride for free, which makes me feel a little selfish. But the beauty of capitalism is that only a small number of people need to like my idea for me to make a whole lot of money. The vast majority of people won't like my idea; only one to five percent of your audience will buy my product. That's perfectly acceptable. All I need is a few people who can't find a ride or who are too lazy to shop around.
