I've already signed up for a HostGator reseller account (so that I can manage all of my own domains with cPanel), created my domain, and installed WordPress. I'm now in the process of installing the necessary WP plugins, finding/creating a good theme, and finding my source data and relevant affiliate programs. In other words, I'm barely getting started!
For all of those that are sitting back and not doing anything, I have three words for you: TAKE ACTION NOW! It feels so great to know that I have taken the first step toward reaching my goals. I'm not fooling myself into thinking that this will be the cash cow that I've been looking for, but I know that I will gain immeasurable knowledge in the coming weeks.
Wish me luck!
