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.
This is for people interested in optimizing for academic fame (for a given level of talent and effort and other costs). Instead of trying to get a PhD and a job in academia (which is very costly and due to "publish or perish" forces you to work on topics that are currently popular in academia), get a job that leaves you with a lot of free time, or find a way to retire early. Use your free time to search for important problems that are being neglected by academia. When you find one, pick off some of the low-hanging fruit in that area and publish your results somewhere. Then, (A) if you're impatient for recognition, use your results to make an undeniable impact on the world (see Bitcoin for example), or (B) if you're patient, move on to another neglected topic and repeat, knowing that in a few years or decades, the neglected topic you found will likely become a hot topic and you'll be credited for being the first to investigate it.
This reminds me of the story of Robert Edgar, who created the DNA and protein sequence alignment program MUSCLE.
He got a PhD in physics, but considers that a mistake. He did his bioinformatics work after selling a company and having free time. The bioinformatics work was notable enough that it's how I know of him.
His blog post, from which I learned this story: https://thewinnower.com/discussions/an-unemployed-gentleman-scholar
