Why you should have a side project
I really think with a proper full time job working long hours its unrealistic to spend much time on any side project. Its much healthier to try to spend time with friends and family, or hobbies. If you have young children there is little chance.<p>What everyone should strive for is the side project at work. Making new tools, monitoring systems, refactoring some library, user friendly applications, experimenting with new languages. Google is famous for the 20% project, but most people can get away with spending a few hours a week on whatever they want while working. If you deliver something useful its also a good way of getting recognition.
