A Munchkin is the sort of person who, faced with a role-playing game, reads through the rulebooks over and over until he finds a way to combine three innocuous-seeming magical items into a cycle of infinite wish spells. Or who, in real life, composes a surprisingly effective diet out of drinking a quarter-cup of extra-light olive oil at least one hour before and after tasting anything else. Or combines liquid nitrogen and antifreeze and life-insurance policies into a ridiculously cheap method of defeating the invincible specter of unavoidable Death. Or figures out how to build the real-life version of the cycle of infinite wish spells.
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
I've always pretended to be in order to get whatever skill I've needed. I just call it "putting on hats". I learned to dance by pretending to be a dancer, I learned to sing by pretending to be a singer. When I teach, I pretend to be a teacher, and when I lead I pretend to be a leader (these last two actually came a lot easier to me when I was teaching hooping than now when I'm teaching rationality stuffs, and I haven't really sat down to figure out why. I probably should though, because I am significantly better at when I can pretend to be it. And I highly value being better at these specific skills right now.)
I had always thought everyone did this, but now I see I might be generalizing from one example.
I learnt skills in high-school acting class that I use daily in my job as a teacher. It would be a little much to say that I'm method acting when I teach —I am a teacher in real life, after all—, but my personality is noticeably different (more extroverted, for one thing). It's draining, however; that's the downside.
