I say, lifgaurd or pool, gym, car wash? dunno, bartender
, summer camp for kids.. lots of young women like to volunteer and do sh*t like this to help others out. Plus, we generally, like kids.., anything outdoors...forget being a movie attendent or anything dorky, including ice cream shops and pizza delivery boys.. Those things will not attract hot women. sorry.. JMO..
Others include home depot, restaurant (but not cheasy), or anything involving charity.
Just ideas, good luck. But finally, I say pick a hobby that you really enjoy. That way you stand a chance of meeting someone that you actually DO click with. Again just a thought...
