The hope that one of my side projects will some day succeed, and I can leave my 9-5 is the only thing that drives me. If I said, "welp, legal" i'd die inside. Some people have church, I have side projects.
I went through a tough time when I wasn't sure if I wanted to be software engineer anymore. Working on my side projects not only made me go through that time, it made me truly happy. Reminded me why I am in this in the first place.
