If you don't know about the Multiverse Theory, it is a idea that every possibility, action, choice, or idea is used or not in an alternate dimension.
So, Think about what you want to do and a different you, or another person is doing/done/will do in a different Universe.
Out of all those, there is one where people ride raptors to work, get payed in avocados, women are always hot and/or always nude, Music never sucks, superpowers exist, The doctor has you be a companion, Douches are tazed on the spot till doucheness fades, Games are only made/approved by Gabe Ben, Free internet, no war, no religion, getting whacked in the balls doesn't hurt, Stubbing your toe is not painful, Twilight books never existed, Morgan Freeman narrates your life, you live forever, Clint Eastwood taught you how to be bad-ass, and the National beverage was your favorite alcoholic drink.
But on the other side of the spectrum there could be everything wrong, I'll let you imagine your unlucky alternate's personal hell.
TL;DR There is a better version of you that gets a bitching life. There is also one that is WAY worse off than you.
