I love this! As I take the very same approach. Side projects for me are often just an excuse to try something new, learn a new discipline (language, framework, etc...). Moreover, you can often change what "finishing" the project means to yourself. Maybe it means just gaining enough knowledge to do something else (maybe something related to your day to day work). At the end of the day I get value out of my side projects. The only one who suffers is Github for having to host code indefinitely that I usually won't go back to :p.
