> Always have pet projects. I strongly don’t agree with this one. In my opinion, a well rounded individual will have hobbies and a life outside of programming that won’t leave time for pet projects. Having said that, I do have a pet project that I’ve been “working on” for about 15 years. Maybe I’ll find some time to make some progress on it after I retire.
