be yourself and don't lie. if your normal self is lying, reconstruct yourself to NOT lying. otherwise no matter how beautiful or ugly the woman, you both will have a horrible life together. honesty -- in the end -- is the ultimately most important factor between two people.
if you're a bar person, find her at a bar. if you're a church or synagogue person, find her there. don't look for a woman in places you are unfamiliar with or uncomfortable with. do not attempt to change yourself, but DO forever work on IMPROVING yourself.
don't become hypocritical. you can't go from being a barfly to a preacher overnight, but you CAN improve the quality of the bar you hang out in.
most importantly - if you WANT NO CHILDREN make sure she knows that in advance. you can both help make the world a better place.
