Most of the time I don't wait at all. I know through painful experience built up over two and a half decades of gaming that if I don't see the solution to a puzzle immediately, or within my first three attempts at the absolute most, I'm not going to see it at all. My mind just doesn't work that way. There is no struggle, no gradual realisation, and no satisfaction - I either know it or I don't. This is one of the reasons I avoid games that are heavily puzzled-based: they're either extremely boring or damn near impossible. It's...weird. I've always either understood puzzles immediately or I've never been able to get them no matter how long I stare at them. Usually it's the more abstract ones that frustrate the hell out of me. Give me a block puzzle and I'll have it done quick enough. Ask me to raise and lower water levels and I'm probably going to scream before I start watching videos or reading guides.
I will admit that I've based this philosophy off of getting hopelessly lost and stuck in games when I was younger, so it might be different now that I'm older and (hopefully) wiser if I was a little more patient, but here's the thing: as a kid, I had time to get lost and stuck. As an adult with a job, a partner I want to spend as much of my free time with as possible, other hobbies I enjoy, and a backlog of literally 200+ games that is only increasing because of my terrible compulsive spending habits, I don't have the time to spend hours on a single point of a game. Or the willpower. Maybe it's supposed to be part of the experience, but if it IS, then it's not a part I care for. Any game I play it's not a core part of the experience anyway, so what does it matter? Honestly I've always hated it when puzzles are shoehorned into video games, because they're never a welcome distraction. They're almost as bad as minigames.
Outside of puzzles...well, it really depends. Older RPGs I often don't play without a guide anyway because they're frustratingly obtuse sometimes. I don't have time to talk to every NPC in a specific order to progress the story, thank you very much, Dragon Quest. But it's in my nature to explore EVERYTHING where I can so quite often I don't really get stuck at all - either everything is signposted for me, as is the way in modern games, or I just find things in my exploration to uncover sidequests and secrets. I can't even remember the last time I got stuck on a boss battle because I tend to overlevel. It's almost always the puzzles that will stop me in my tracks.
The way I play games is weird, I guess. I want a smooth, enjoyable playthrough of whatever I happen to be playing, so if I need to use a guide to progress I will. I've outgrown my "I can do this all by myself!" phase because it never really brought me any joy and it damaged my miniscule pride far more than I could take because quite often I couldn't do it by myself.
