Right now, it's overcoming my unbearable procrastination/lethargy/aversion to/for anything that even seems unpleasant. If I can't do hard work, I'm basically useless for whatever I have planned anyway, so it's critical.
On that note: Wasn't there a high school group who essentially manufactured a nuclear bomb casing without the critical exploding and fissioning bits?
I was actually somewhat interested in dath ilan as a sort of vague social model before reading these comments, but afterward, I think I'm perfectly fine with Earth. I suspect I'd be absolutely miserable there; the fact I'm a huge fan of hyperidealized art is the primary reason.
