I have to force myself to not fall into the trap of trying to play a "perfect" game and instead to just let happen, what happens. Blundering through content and accepting temporary setbacks is more fun than following guides or save scumming.
But it also depends on game design:
With bg3 I missed a one of a kind item in act 1, a staple dnd item (ring of protection) that I was locked out off because I did quests in the "wrong" order. that gave me some anxiety, after which I started checking the wiki page before starting a new zone, which eventually sucked the fun out of the game, after which I abandoned my first playthrough.
And then I found a mod that randomizes all loot, so I can just let happen again what happens, without that anxiety of losing access to unique loot because of game design.
