Step 1 to get girls to like you is don't be fat, be at least a little muscular.
Step 2 is a good haircut. If you don't know what to do here, find a barber shop run by Puerto Ricans or Dominicans; they take their grooming very seriously. White hipsters can give you a good haircut, but they're not gonna trim your facial hair in a modern style and if you don't know exactly what you want they're probably not gonna be much help.
I hate to say it but shops run by an old white guy only give one haircut and they're gonna shave your face. You aren't a GI coming back from The War and this isn't the 50s, that's why you don't see many of these places, avoid.
Step 3 stop dressing like a child. No more graphic tees or running shoes.

TL;Dr: stop being fat, get a decent haircut and fix your neckbeard, quit dressing like a 5 year old.

Remember the picture of the chapo traphouse guy who had a heart attack, dressed EXACTLY like the literal toddler standing behind him. A lot of you are exactly like him but with different politics. Stop it.
