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.
First-time poster, long time lurker. This discussion piqued my interest.
If you have your own business, a very cost effective way of promoting it is to get a part-time job, (or 'side quest' in D&D parlance) that involves delivering something such as catalogues, phone-books or even takeaway food or a paper-round in the location where your business operates. You can easily slip in your own flyers or business cards in along with whatever you are delivering. The wage from the part-time job will easily pay for the extra printing and mileage costs. I do this and my p/t employer hasn't found out yet or even explicitly or implicitly forbidden me from doing this; in fact, my p/t boss is pretty wily entrepreneurial sort of chap so he would probably actually approve so long as I am still good at his job.
