This is of course oversimplified. The argument seems to me like: 1) If you love what you do, you will care. You will go the extra mile to do it right. 2) After a couple of years of doing what you love, and caring, and improving every day, you will be very good at what you do. You will be able to beat most competitors (who don't really care and are in for a quick buck anyway). 3) Assuming your clients can tell the difference, you will never lack work. 4) Assuming your market is big enough to support you and your more important competitors, you will be able to pick clients, and rise your fees, and have lots of work anyway. 5) Then money follows the good work. Now, there are 2 big assumptions here. One is that the world will be able to figure out how great you are and how lame are most of the others. If they cannot, or doesn't care, you are in a lemon market. The scam artists grow rich and the good practicioners get exploited. Not a nice place to be, unless what you love is take advantage of other people. The other big assumption is that there is enough demand for what you love to do. By example, if you love classic music and want to be a piano concertist, good luck with that. There is not enough demand for that skill to support but a handfull of performers. Unless your talent is that of a genius or have all the right connections, you will not survive long enough to actually learn to play well. Again, not a nice place to be. What you want to do if not to do what you like the most. You want to ask yourself what are those things that you like. Get a list of a dozen items. Cut half of those that seem like lemon markets, the cut again by half those whose market is to small. You will end up with a couple of solid options of what you can realistically pursue.
