Maybe, look for "Butterfly effects[1]" happening around you, i.e., small insignificant events that have huge, enormous after-effects.

Essentially, if there were a system that could send information from the future to the past, the future agent would want to be "as discreet as" possible, while still achieving "nearly perfect" outcome. Note that the future agent has the advantage of reiterating over and over his/her choices, because, well, the "future-future" he/she can still send a signal to his/her past about want went wrong the previous time.

This happens to be a common plot for a lot of various time-travel movies and TV shows like Dark, Umbrella Academy, etc.
