1. A lot of the good ones are taken.
You know that really cool girl, the one you've had your eye on for some time? Sorry, pal, other guys see her, too. And one of them got to her before you did. It's shitty, but it happens. Often.
2. Meeting women can be difficult.
Big cities are cold and impersonal. I live in Canada's largest. I also happen to live in a part of it where the median age is likely in triple-digits. It actually surprises me when I pass an attractive woman within ten years of my age walking down my street.
3. People are their own worst critics.
You spend all your waking hours obsessing about this, that or the other little thing that's wrong with you. But, we all have our flaws. Nobody's perfect; hell, Tiger Woods may be the best golfer that's ever lived, but the guy's basically got OCD. So, relax.
4. Guys make the first move.
Women have periods and babies, and neither of those are fun. It's typically the guy's responsibility to initially break the ice. I'm honestly not sure who has the easier job here.
5. It feels awesome to have your ego stroked.
Even if it doesn't lead anywhere, it can make a guy feel like he's king of the world if he has an extended conversation with a woman he finds attractive.
That's all for now. I'm sure I'll come up with more, eventually.

Upon further reflection, I think #1 is probably the most significant, at least in my recent experience. Jesus, if I had a nickel for every time I talked to a really great girl and she slipped a "myboyfriend" reference in there, I could quit my job and buy a solid gold house. Why is that? Are attached women natually more open to conversation (especially with me)? Are they more at-ease, knowing they can whip out that ace-in-the-hole anytime they feel uncomfortable? I don't believe in things like curses and karma and such, but I swear this has happened to me much more than my fair share of times.
