Hi Daniel,
Welcome to 5 Star. What you are going through is common and if you buy and read every ebook by every self proclaimed affiliate guru you will stay confused.
Here are 3 that I recommend. Pick the one that you think would be best for you and work that one system just to get started. Then you can get more creative and branch out a little. The very 1st step is to get started.
www.affiliateclassroom.com. Free or low cost trial. Step by step training system.
www.jamesmartell.com I know many affiliates that have made lots of money with his system.
www.sitesell.com Another proven system.
