pencils - i would say overrated (pencil writing doesn't look pretty and it rubs off), but they're probably better for the environment. marriage - overrated. roombas - dunno. cash - underrated (having the option of anonymity is great and we won't necessarily always have it). electric cars - from what I've read from everyone who's ever owned or been in Tesla, way underrated. school - overrated (it's child abuse). social media - rated just about right, imo. tattoos - overrated
