I second everything everyone has said but keep in mind that what matters is not where you are in terms of weight lifted but where you are going and the quality and purposefullness of your work. Nothing else is important but the road, but you can only judge it's validity by your progress. It's kind of a ''mindfuck'', because you might as well be wasting your time and not getting any results while thinking you are doing something right. But does it really matter if you squat 500 or 600lbs right now? I think the answer is being honest with yourself..
Sometimes I wonder if what I was doing in the gym years ago, when I was 18 or 20, squatting 185lbs or such was worthy. I was weak(er) and lifting small weight, so was it unworthy and a waste of time? Was it worthy only as part of a whole and in relation the to future where I progressed to lifting bigger weight or is it also when isolated from a future that is uncertain? Did I waste my youth training alone in an empty gym at night because it was only ''weak'' weightlifting? I like to think it was not and that what matter is right now.
Yes there is some guys built with huge hips and calves, bones, large monkey face and whatever that lift naturally more than you without much effort and work. Even if I don't want to have their builds and rather stay weaker and exactly the way I am naturally (let's face it they are ugly), it doesn't really matter that they lift more. Them being stronger than me, or weaker, uglier, better looking or whatever doesn't change the validity of what I do. For some reason I don't envy those people. It's just a gut thing, and not only because they aren't good looking.
That's also why I don't care about going into a bigger pond (gym). What I care about is me lifting weight and I don't need anyone around me to know internally if what I am doing is good or not. You just need to be honest with yourself. We all know the feeling when we had a great energising workout. Have you ever seen Dave Draper's training? It's the most outdated thing, but he is the real deal and he has a lot of passion. It's a spiritual thing for him. He is part of the great ones. That is also why I really don't care if people bullshitting or not their numbers on the internet and about teen apes from arkansas.
So I think if you lift honestly with a purpose and feel some joy doing it you are getting somewhere and the rest doesn't matter. Right now I think I might be putting my general anxiety into a post actually.
