I know that people tend to get more inspired or have more ideas the less time they have

That's one of the weirdest things, isn't it? I wrote the bulk of my fanfic while working 2-3 jobs; as soon as things settled into an easy 40-hour week with one non-challenging job, zip. Zilch. It's like my brain is an adrenaline junkie and just can't be bothered if it's not flailing crazy times.

That said, I'm trying to land a second job for...reasons. ~_^
