Ever heard of the Many Worlds interpretation of quantum mechanics? It's an actual scientific theory that says for every single decision-point in time, nature makes all possible choices and our brains are only capable of "seeing" one of those choices, which manifests itself as our timeline. All other possible choices exist in alternate universes that are tantalizingly just out of our reach. I take comfort in this bizarre theory: if true, it means that somewhere out there is an alternate version of myself who is a billionaire living it up on my own private island, enjoying the good life I can only dream of. :-)
