"Literally everything matters" -- not necessarily. The world is full of stable attractors that turn any number of small perturbations meaningless. Coffee turning bad might influence you decisions a few hours down the line, but likely not months, being half a degree warmer or colder likely won't influence you at all. Meeting an impressive person as a child might change you greatly, but the other thousands of people you've met in passing likely won't affect you much.
