We can't all follow our dreams. First, the world won't work if everybody refuses to do anything that doesn't interest them. There just aren't enough truly passionate career janitors and retail salespeople in the world. Society would collapse on that alone. Second, for every successful musician, there are at least a thousand garage-band wannabes who will never make it, despite being just as hard-working and talented. There is just not enough room in the market.
