A hundred years ago, "everyone" wore a hat. If everyone meant men of a certain social stratum in certain cities. And people wore the hat because everyone else did.
And everyone is taking the day off and everyone is watching the big game and everyone is busy checking their status on Facebook.
Except that in other time zones or other communities, everyone isn't doing anything of the sort. And on Saturn, they've never even heard of it.
Peer pressure is a little like barometric pressure. It's constant, it's all around us and we assume that it's universal.
If it's not helping you achieve your goals, ignore it.
