When I first found Andreas' forum a couple of years ago, I looked through posts of his that interested me.
You can type any subject in the google box in the upper right corner of this page. If you put Andreas first then the subject, links from his forum will come up.

You'll get better following Andreas' book. I did and so have many others.
