[Don't read this if you can't accept the reality -Exactly it's 90% about the face, you should lose as much fat as possible to see your jawline, get plastic surgery for uneven parts and start mewing to make your face shape better- Don't read this if you can't accept the reality]
Also just dress well, take care of your self (skin,beard etc), smell good, get a nice modern haircut, improve your social skills by exercising it, make a lot of friends, find new hobbies, set goals
