Guys who are under 5'8 or so definitely have a disadvantage, and if you're 5'4 you really did get the short end of the stick (no pun intended).
I say this as someone who is a hair over 6', too. I remember once I talked to a 6' woman on OLD who literally insulted my height when I made a joke about her wearing high heels around me (she straight up sent "hahaha you think you're tall?" and unmatched me). Self-centered/solipsistic/BPD women literally do not see other shorter men as human beings.
Sure, mindset can change things, and not all women care about height - but men who insist people like OP just need to "be different" are missing the point - it's still a huge disadvantage to overcome. It goes without saying that, wealth, status, charm, CAN overcome it, but to deny they don't have an innate disadvantage is just dumb.
That said, if I had to pick between being 5'4 and having a 7.5" **** or being 6'3 with a 2" ****, I'd probably pick the former. All I can say is be grateful for what you have.
Yeah it is a disadvantage, particularly as its one that can;t be changed as such. But, unless you're really unattractive facially, there is evidence on here and from what I;ve seen that short guys can still get laid in the west.
Tall guys certainly don;t have it on easy street (assuming most aren't male models). You may get pass on height, but if not good looking, confident, smooth, high status, women will still regularly reject you. I'm saying this from experience as being 6"2, ripped, above average looks etc.
I do empaphise with OP though, must be a real thing on their mind as its totally out of their control. The main points are, there is NOTHING OP can do about height, but by excelling in other areas he can greatly enhance his chances of being successful. If being with women is that important, then he needs to be driven to raise his game with variables that can be changed, or move somewhere where the average height is much lower.
One of my friends is 5"6 and he's always had a bit of a downer about his height, so 5"4 must be tough pill to swallow, but he's frequently had g/f's. 1 was where we used to work, abouut 10 years younger, decent looking and had massive t1ts, who just about every man in the office fancied. He just asked her out and were together for a couple of years. He is/was lead singer in band which no doubt helped. Very clever chap, with charisma/gift of the gab/articulate (wouldn't stop talking all the time!), never any awkward silences with him and decent looking enough, square jaw, but not exceptional looks wise. Can barely recall a time when he hasn't had a g/f, wife, been dating - all of them around 7ish looks wise. And from I gather, most of that in recent years has been from OLD.
My memory may be wrong here, but iirc, OP has previously given impression he's not that confident/outgoing, at least with women. When I was like that at 6"2 I barely got anywhere with women, so at 5"4 he has no chance I imagine unless dealing with 5 and lower on looks/body scale. Not sure what to suggest exactly as don;t know the OP, but stuff that makes him more confident, likeable (by women), outgoing like weights (being lean not only improves physique but usually facial features too), martial arts, toast masters, along with status things like career/business?? Good hair cut and style is quick, easy one to implement for starters.
