Starting to Learn the Principles of Marketing

As I'm starting to understand it, as an online splinter marketer, this is what you do--correct me, if you're wrong.

1. Pick something to sell.

2. Market yourself well.

3. On your site, praise your "something" to high heaven, going into exquisite, and loving detail about it--making it seem cooler, and more unique than at the store you bought it.

4. Sell said "something" at a ridiculously high mark-up price.

5. And, a small, but decisive sub-group of your audince--also known as patsies will reward, via paying through the nose.

Any questions?

As I've been studying this, I have been wondering if this can be of any use to me, given I'd like to make money on the internet, but don't wish the feel like a total shill. I wouldn't feel honest, and I'd feel like a taker, anot a giver.

That said, a good infomercial, like those of ROn Popeil, were part product review, weren't they? It would be fine if there were something I could believe in selling, but I don't yet see it.

I've been making stuff for YouTube, but I still don't understand if I can really market myself on it, because I'm still not clear exactly wat it takes. I enjoy making things that make myself, and others laugh, but I fear I'm not focused, enough.
