Horse doody. As we perceive it, as we choose it, as we make it to be, time is a fucking linear line. You only have one timeline. You only choose one time. Every choice you make matters. Those pseudo-intellectual assholes will tell you otherwise. They will attempt to make you think that time and choices branch into some weird quantum tree of a multiverse, where all things are possible. But guess what? Even if they are right, you still live in your own time line. You still live with your own choices. Branch off into a different timeline if you can. Time is a flat circle. A pancake is a flat circle. See how profound I am?
