But if leaving this job is not a viable option at this time, I would say: Take advantage of your innate strength as a human being, which is to say, intuitive thinking. You're never going to match a machine when it comes to quantitative analysis of huge bodies of data.
Some changes must be taken into account. Some resolve themselves over time. Others don't matter.
It's also helpful to make a list of "all" possible inputs/tasks/focuses of attention — then, out of every 5, select 1. And out of those, select one of every five. That gives you (roughly) the top 4% of important things.
I also read something on HN today that resonated [1]: "you can only ever actually be doing one thing" so pick anything that "would be worthwhile to do right now, without any expectation that you know what might be 'best'", do it, and repeat.
FOMO is a b####, but virtually everything is unimportant. And with respect to important things, consider the unimaginable vastness of the universe and how trivial even the most important things are in comparison.
