This is why I'm a firm believer in [Great Man Theory](https://en.m.wikipedia.org/wiki/Great_man_theory). There is so much entropy inside of every person's mind, and the world is so volatile, that very few decisions (rational or irrational) from a few people (sometimes just one) can change the course of history drastically. We'd live in a very different world, had a lot of improbable things we saw hadn't happened, and there's just as many potential events that you can't even consider, that could change the future we will see. This makes all geopolitical predictions impossible if your trying to predict more than a single black swan event in the future.
This should be the biggest whitepill for everyone. Literal nobodies have changed the course of history completely and utterly, many times. The only thing it takes is dedicating your life to it. You have the power to change the future for the whole world, but it ain't a part time gig. You will die in the process or become a household name, no in between.
