The biggest side project I am currently working on was an accident. I used one site (dance calendar) every day, because I do lots of couples dancing. I had some ideas on how to improve the site, but did not want to compete with the existing site. Then the site went down, the previous operator did not want to continue running it, and I worked together with him to get the new site up and running. I think the world is full of ideas to work on. You can look into almost anything, and see that existing ways of working and systems are mostly crap. Just start working on something. Probably you will encounter other problems -- i.e. ideas -- when working on the first one. The biggest thing is not the coding, but all the other stuff. Sales, invoicing etc. I find that tiresome.
