This is not meant for the major stuff, like religion/politics/ethics etc...
This is for dumb stuff you probably should have realized sooner, but still changed how you live your life.
My own stupid revelation was...
It's perfectly okay to doctor/alter fast food.
Looking back I feel like a moron, but would do absolutely stupid things with my fast food.
'Hmm this ins't salty enough... *salt easily available on countertop* ah well"
"This is good but it could be spicier, that would be great." *happily ignores jalepenos and hot sauce in fridge*"
Looking back it carried on for years, even into adulthood, even though it made no sense.
So do you have anything you've done that was incredibly stupid/pointless and more to the point unnecessary, or avoided doing something easy because of nonsensical reasons?
