Lol why mythology?
One benefit that I am aware of is in one's thinking. Gods and heroes are at times still targets to aim for. Fresh new ideas spring from the dust of the old. Superstition examined is, with the right teacher, superstition avoided. The teaching of many different points of view helps understand other people's values. Illustrating a difficult problem with a myth or two assisted me in mathematics and in examining how I view right and wrong (my current obsession with diversity could be blamed on the sheer variety of myths I absorbed).
The second benefit, and one may consistently find even in the absence of good teachers and a clear goal is that it simply provides a much-needed break in between lessons useful for work.
Thus spake Eliezer:
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.
