WHATEVER MAKES YOU CONFIDENT!
Some girls have standards, as in, they will refuse to date a guy unless he has a job, or something along those lines... Similar to I won't date you if you smoke.
We gotta remember some girls are materialistic...
GOLD DIGGERS!
If making 50k a year makes you confident. Then that works...
If money doesn't mean much to you, other things do, like health and personality. Then if you are confident in them you'll come off as confident.
I have a friend who makes like 35k a year. And he does tons of freelancing. So he makes around 45k a year. He thinks money means chicks, so hince he is confident. He doesn't go to the gym, the denist, washes clothes once every 3 months, dresses like a bum. But yet he is confident... I DO NOT KNOW HOW!
