If women were cars, imagines all the different kinds of cars existing in the world, except the engines, chassis, bodies, gears, tyres and everything else is random. So you would have a Chrysler Neon body with an Audi 4.2FSI engine and some beefy Michelins and a Ferrari F40 with a 1.5 DCI diesel engine. Don't be afraid of the Ferrari because it looks like it could eat the road. What I'm saying is, no matter how a girl looks like, they are just like any other person, good sides and bad sides. You could feel bad if your life was chaos, half finished college, 2 years of work off college, lost the job, roommates in an appartment, no desire to study, can't get jobs you wish for, hate the jobs you could get, but can't because there aren't any, overweight, balding, get sick often, chronic bad breath, no sense of style, a virgin at 24, no actual prior relationships.... and then you want to ask out a straight 9, boobs, a$$, you name it, she's got it, well dressed- now let's say by some miracle you do get a date - she's a chemist, phd. passionate about her job, many hobbies, works out regularly, bought her own apartment, has small parties often, travels abroad, dances socially, her ex was a brain surgeon, and loves to cruise in her '79 stingray. And you just sh!t your pants.
Now, if you have your life close to where you want it to be, all tidy and neat, you have some semblance of a man with style, are well groomed, have some financial stability, then as long as you look presentable, your looks do not matter. If 1 would be scary ugly, 2 ugly as hell, 3 Robert Pattinson ugly and 10 would be orgasm inducing handsome, then from 3-10 can get any girl they want. So, first get your life together if it isn't already, then KNOW that you can get a girl as hot as they come, just not actually ANY girl. Some are in a relationship, some are looking for someone with an abusive personality or an alcoholic and won't respond well to your coolness, some will have some tragedy happened to them and aren't over it yet, but anyone normal in a normal state of mind.
