Side projects are not a matter of "having an unfulfilling day job". A side project is simply scratching an itch.
That itch could be something that bothers you, or it could be simple curiosity.
I have a very fulfilling day job (I'm a co-founder of an awesome startup, which makes it more of a fulfilling day&night job), but that doesn't mean I won't explore other things, try out new technologies, find something that sucks and make it better, latch onto an idea and build it while thinking "how hard can it be?" (Answer: it can be VERY hard)
Side projects are an outward expression of people who are hopelessly creative and just can't help themselves. The CONTENTS of those side projects demonstrate how organized, focused, and disciplined they are.
