From the beginning I created my own theme. I wanted to tinker with everything and was happy to find out WordPress did not prevent that. I created a lot of functionality on top of it, mostly for my personal use. Like a database of books I had read and was going to read.
While working on my day job as a Web developer, I did some freelancing on the side to build a couple of small sites on WordPress. That made me learn WordPress even better.
WordPress gave me ideas. For six years, working with different CMSs and other projects, I took a lot ideas out of WordPress and used them with commercial projects.
