A charismatic 5'7 guy who can speak articulately and is low inhibition would do way better in a social environment than a high inhib 6'4 guy who has a slight stutter and is timid.

And I (early 20sM) say this from experience too, im currently in post grad school here in the U.S. class size is about 180ish, we had our orientation week and i constantly see short guys hitting it off with girls with zero issues meanwhile no matter how much or hard i try, i may as well be invisible. Maybe I can get in a basic 2 min convo but then ill never talk to them again. Thats the extent of my interaction with women so far. Even if they see me again walking down the hallway they act like we've never met before its brutal.
Im quite average/slightly above average all else be considered, im not facially deformed, i shower and always have on a new outfit, i dont have acne, i dont have physical disabilities (i actually go to the gym a lot and im 205 lean), etc etc. I dont have anything else that would deter people from wanting to speak to me, its literally just my personality that I have to work on which i find is really hard to change.
most short guys who complain about height are more often than not just high inhib and ND asf.
