Thanks to Scott Adams for coming up with a great way to explain this . . .
In a world with too much of everything, only those products and services that generate passion have a chance in hell of making it.
But here's the kicker, the opposite of passion isn't apathy. The opposite of passion is "I like it."
So if you are an artist and you do music/painting/plays that everyone "likes" you are in serious trouble.
Because most people don't go out and buy things we like, we go out and buy things we love.
Seriously, think of the list of things you like. It's probably a huge list of things, which means you have plenty of options to choose from when you want to get something you like. For me, when I think of restaurants I like, I can think of maybe 50 of them.
Now think of something you love. When I think of restaurants I love, I think of maybe 3.
So if you are a restaurant, being in my "love" group is a lot better then being in my "like" group.
Therefore as an artist it is better for you (as someone who wants to make money from their art) to have 10 raving fans of your work then to have 100 people who like your work.
The challenge, of course, is that creating raving fans is difficult. You have to work harder on your art to make it challenging, beautiful or thought provoking.
But if your work isn't all of those things (or at least one of those things) then it runs the risk of being lost in the clutter of life.
