Your fandom lets you develop business sense, a sense of customer service, and entrepreneurship. If you think I'm done talking about the professional advantages of your hobbies, it won't surprise you that I'm not done yet.
Fandom teaches you courage.
That may sound strange to some people – until you think about what fandom actually involves.
I know Hello Kitty has fans. In fact, I have to admire Sanrio for creating a sort of Seinfeld of cuteness.; Hello Kitty really isn't about anything. Hello Kitty is sort of a brand of general adorable cuteness and pathological amounts of pink. It's just that when it comes to it, there's not a whole lot of "there" there. Hello Kitty just sort of is.
She's darling, as is her collection of friends, but she's not about anything.
Sanrio's success aside, you don't want to use her as a role model for personal branding. Even if you like Pink. A whole lot of Pink.
You're not happy with your job. You don't like what you do. Worse, nothing out there in the job market that appeals to you. The final kicker is that of all the jobs you've heard of none may appeal to you. You've got all this energy and skills but nothing out there is what you want to do.
So let me suggest, my fellow progeek, that maybe it's time to invent an entirely new job.
