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.
(The below is stated with no modulation for my level of confidence, which actually isn't very high.)
MDMA is a useful way to improve social skills permanently, or help make you more emotionally available.
While under the influence of it, you're very empathic, and very socially fearless. The experiences you have talking to people in this state can then transfer to when you're sober. For instance, you might notice that your openness is well-received, which lets you see that you've been under-confident.
Many people do something similar with alcohol: they learn to socialise when drunk, and that makes it easier to socialise when not drunk. I believe MDMA is better for this purpose, because it doesn't inhibit your memory at all, and you're more "yourself" than when drunk.
To get this benefit it's important to take a well-tolerated dose, and not to drink much: you don't want to be a mangled mess, or the next day you'll just be embarrassed, especially because you'll be mildly depressed from the come-down.
I've found MDMA to be quite addictive, and most users have trouble controlling their use once they are on the drug: they'll re-dose, even if they hadn't planned to, once the first dose begins to fade. So this "hack" is far from free of danger. But I believe the cost/benefit is still better than alcohol for many situations.
What's your dosage schedule? Have you noticed a decreased ability to experience pleasure?
