It has always been my thing to make your hobby your business and many have succeeded in creating great websites and blogs doing just that. It can be anything, even collecting old tin cans, as long as the passion comes through.
With your heart in it writing, composing web sites etc. comes easy because things flow out naturally. Once your site follows your heart you know what to do, how you want to market your product, where to go for buyers and how to turn them into clients.
The client respects you because you display credibility, are honest in your goals, and you offer quality and service rather than someone's else's ideas. Of course you will never not need the WF for learning techniques, and the other things required for generating a good business.
Good service follows passion and doing the right thing.
That's my take on it.
