will I gain respect from other men and have a chance of a relationship if I'm still 5'3 with a decent face and frame?
You're in a very brutal situation, matecel. I'm 5'7 and regularly wear elevator shoes / lifts that give me an extra of 2-4 inch in height (depending on what exactly I wear at the moment); I'd rather not leave home without some form of height elevation. When I use no height elevation at all, foids contemptuously dismiss my very existence and men act all antagonistic and insulting towards me. If you haven't bought yourself some height-frauding equipment, stop
immediately doing whatever it is you're doing -- don't even read my comment till its end, like nigga, just close the goddamn tab with this website on it -- and rush to buy yourself height elevating shoes and lifts off Amazon, Ebay, AliExpress, or whatever store you like.
Your situation is way harsher than mine, however - you have legit truecel height. You absolutely can't afford to be too fat or not muscular enough, you must be Norwood
0, your skin must be top-notch, you better have visible abs, you need to drain your wallet clothingmaxxing, get plastic surgery to fix whatever minor or medium or major flaws your face has, get rid of your glasses if you're myopic (preferably through surgery, which is supposed to be permanent), and besides all that, you need sharp charisma and wit aka "game," good money, an impressive job, your own nice apartment, a decent car, travel experience to brag about, autism-free neurotypical behavior, basically not being a low-functioning loser on
any level. And even then, it's an
extreme uphill battle with no promise of success.
It is likely that you'll need to relocate to somewhere in South America or South East Asia even after you truly maximize your looks potential.
