Location, location, location. Your odds drastically decline in Butte, Montana as opposed to Miami, Florida. Hot women have a curious tendency to relocate to where the action (not to mention rich men) is. Statistically 66% of Americans are overweight and a full third qualify as 'morbidly obese', in my book this puts 66% of the U.S. population (adjusted for gender) out of the equation. That leaves 33% of the single females in contention, adjust for only single women in my target demographic (18-30) and childless, maybe I'm at 20% of the population (females only again).
There are ways I can increase my odds with that 20% however. If I keep myself within that 33% of in shape adults or exceed the fitness average of this group I set myself apart. I can of course develop DJ/PUA skills, but if I lean towards self improvement and I have verifiable social proof of such this makes me more marketable. And last, go fishing where the fish are - truly beautiful women have a marked tendency to leave rural areas in favor of the glamour of large metropolises. Can't leave just yet? Take vacations in these places. As a side, consider leaving the country on vacation and see what women of other cultures have to offer.
