Try to manipulate the size of the pot through your bets, checks, raises, etc., so you're playing big pots with big hands and small pots with marginal hands. Seems obvious, but a lot of times people get carried away with slowplaying monsters and making big desperation bluffs, or play average-at-best draws super agressively (basically getting the whole idea backwards).

As far as foresight, just think about how future action can go down. IE, say you flop a set and you want to attack somebody's entire stack.

Say the pot size is 14bb, with 100bb effective behind. Heads up on the flop, out of position. What's your plan here? Of course this question is so general it's pretty much unanswerable, but lets just try manipulating the pot and save different lines we can take for another day. Say we lead for 10bb, he calls, pot is up to 34bb. now we lead for say, 26bb, he calls, pot is up to 86bb. Now we stick in our last 64bb, and we're allin. This is 3 bets, and this can be accomplished so many ways. Lead+lead+lead. C/R+push. Lead+crai. Lead+c/c+open push. Etc.

I'm tired btw and usually when that happens i get down a bunch of ideas but it comes off as being all over the place so if that's the case i apologize.
