I ruminate on a lot of "what ifs", but it's not what-ifs of the past, it's the ones coming up. I get very annoyed having a lot of "what-ifs" that's in the past (i.e., nothing can be done about it), which means, the present is about making sure to minimalize the "what-ifs" of the to-be-soon past, and the future to come is in part about being aware of its "what-ifs" to fulfill it to its optimal capacity, and to get excited, giddy about them. Will it turn out the way I'm anticipating it?
I truly think there's foresight, to a degree. It's not so much about controlling the future, but, seeing how I imagined it playing out (my prediction), doing so, given what I knew of the present, and how it has worked in the past. Cause/effect. Each moment, if aware, is capturing a domino piece falling, and you can likely predict the direction of fall it will set off, for the next piece coming up.
