However, to answer your main question, yes it is possible to make money by just sending traffic to affiliate programs BUT its a lot of work.

You need to diversify at first and try your hand at pretty much anything and everything from TGPing to building free sites, building AEN sites to working the search engines and again, its going to be tough.

However, the benefits of this trial and error phase far outweight the bad as you will find something that you excell at and, once you have found it, you should become a master in that field and grow your business further.
