"To draw a man I simply picture a woman and remove reason and accountability." - As Good As It Gets
Zylon already corrected it, but he didn't put it into context with the question which is rather important.
The scene was about a woman asking Jack's character about his writing and it went like this:
"How do you write women so well?"
"I think of a man. Then I take away reason and accountability."
Which is very very true as far as I'm concerned when it is applied to a majority of the general population.
When I said good girls, I meant easy going girls. I don't think it's that easy to hook up with a easy going girl and yet normal. On top of that, who says good girls can't be fun? Sometimes people could be so wrong about that fact 
Quality is hard to find, which is exactly why there aren't that many "good girls" around. This is a principle that also moves with the times and periods of life in general as far as I can tell anyway.
That aside, all the candle wax on my genitals doesn't change the fact that after the session I still have to live with myself and my choices. Just not worth it when it comes down to it. As far as seeing the evil in people goes, that's the easy part. The hard part is seeing and judging the good in them. And finding someone with the latter without the former who is balanced, is... **** hard.
