In my perfect dream world, awesome girl, you've got the following traits.
Intelligence - You're likely well educated, but more importantly, you simply "get it" most of the time. You're able to competently discuss a variety of subjects, and if you're ignorant in a certain area, you've got no problem admitting it - and you likely start asking a lot of questions, because you like to know and understand things. You love to learn, and you realize learning is something you do every day, not confined only to a classroom setting or reading a book.
Comfortable with yourself - You don't talk a lot about how amazing you are, because you don't need to. Sure, you have your insecurities (we all do) but for the most part you're pretty aware of your strengths and weaknesses, and if something about yourself that you can control really bugged you, you've probably taken steps to correct it. You're happy with who you are.
You're socially aware - You can likely read people pretty well, and you can generally get a good idea of what type of person you're talking to within the first few minutes of a conversation. You're perfectly comfortable if you find yourself alone in a group of people you don't know. You can and do get along with a wide variety of people, and actually enjoy said wide variety of people. This ties in with the next item on my ever-growing list.
You're versatile - You're comfortable in a variety of different settings. You can get all fancied up to go out for a night on the town, but you're fine with throwing on a pair of jeans and a t-shirt and going to a dive bar with little or no makeup on. You're not intimidated by dressing up in a business suit and can more than hold your own in a professional discussion, but you're also perfectly happy going to the state fairgrounds and watching the demolition derby. (Note: I don't care if you enjoy the demolition derby or not, it was simply an example on the opposite end of the spectrum from a suit.)
You take care of your body/are attractive - You also aren't offended that I'd include this on a list, because hey, physical attraction is important and you realize that. I don't need you to be a supermodel or a triathlete (I won't be either any time soon) but you are active because you enjoy feeling and looking your best. Well, and because being active is fun. You're aware of what you eat - not to say you don't love a good burger, ice cream, or whatever your culinary weakness is (one of mine is the good burger) but you maybe don't eat junk food all day every day.
You're likely somewhere in the general vicinity of my age (you can tell just how important this is to me by how specific I'm being), and you likely have a job that you're pretty good at - you're probably pretty good at most things you set your mind to, actually. You may even have been described by some as "intimidating" due to your general precociousness, attractiveness, and confidence level. This is good. I'd go so far to say that if you've been called intimidating, you're likely pretty awesome.
A little about me:
As you likely guessed, I like to think I have most of the traits I listed. I mean hey, if I sat in my mom's basement playing video games all day, I wouldn't much care how socially aware you are, right? I'm certainly not the perfect man, but I like to think I'm a pretty decent catch on my good days - here's a bit about me.
I'm 35, 5'11'', and while I won't be on the cover of Men's Health anytime soon, most seem to find me attractive. I've got a good job that I actually enjoy doing, and I rent a loft downtown. I'm certainly not wealthy, however. I've got a pretty eclectic range of interests and know a lot of random things. I'm usually pretty useful on pub trivia night.
I'll play just about any sport with a ball and enjoy it, and I'm a fan of most of the local sports teams.
I'm quite social - I tend to spend my free time and my mad money being around my group of friends, who I'm lucky to have, as they're a pretty great group of people. I'm pretty well traveled, and usually don't lack for a story to tell when it's appropriate. You likely won't be embarrassed for me to meet your friends should we get that far. I've got a pretty overdeveloped sense of humor that is wildly inappropriate when the setting is right. I've done a lot of random things. I'll tell you about them another time as we get to know each other.
My goal in writing this is definitely not to have a big checklist, all items of which are necessary for me to respond. I'm trying to give you, awesome girl, an idea of what I find attractive, and if you feel I'd find you attractive and you don't mind what I've written here, perhaps you'll respond, we can exchange a few pleasantries over email, and then meet up for a happy hour drink, a hike up Sabino Canyon, UofA baseball game or really anything so we can see if we click.
