Soy you have a head full of fandom knowledge: films, game statistics, movie notes, fanfic, etc. You're a great raconteur at a convention – so how are you going to use this on the job?
You're going to because your interests give you the ability to make small talk. You've got a valuable networking tool.
I'm a big booster on the idea that you can use your hobbies to learn something – practice your accounting helping out a local con, practice your HTML making a website, practice your writing doing anime reviews. Hobbies are a great way to gain and improve skills.
However there's another thing hobbies do for our skill improvement that makes them even more valuable – they provide a kind of mental and emotional buffer to the stress of learning. This is very useful if you've got a lot of stress to deal with or had some negative experiences with training or education
So there I was, taking a break from being, well, busy, and giant robots helped me get my working mojo back.
I know, you may need to reread that line again.
Essentially I was watching Gurren Lagann, an unusual anime that is hard to describe. It's a giant robot show, a space show, a drama, parts of a comedy, strangely sincere yet with winking nods and references. A big part of the show is the power of fighting spirit and people's emotions to drive them on and empower them. This is an anime that people who don't watch anime won't get.
It was actually quite inspiring, and it struck me that's something we geeks and fans need to keep in mind – we can find inspiration in seemingly mundane things, and that can push us on.
