The population of earth is about 7 billion people.
About half of them are the gender you're attracted to. (Unless you're bi.)
So I don't have to actually do research, let's do back-of-the-envelope kludgey math to figure out the age stuff. 65.9% of the world is between the ages of 15 and 64. That's 49 years. Let's call it 50. Let's pretend that the ages within that bracket are distributed evenly. Let's assume that you're in that age bracket, and you're roughly attracted to people within five years of your age, putting a 10-year bubble around you. So there are 461,300,000 people of the right gender and age.
Let's define the word "gorgeous" as 1-in-100 cute (46,130,000).
Let's say that in this huge crazy world of monkeys and typewriters, for any given person's psychological problems and character flaws, around 1 in a million people finds themselves attracted to exactly that (like "man, obesity in effeminate men really turns me on.")
By this awful made-up math, even if you're hideous and annoying and gross, there are 46 gorgeous people who are literally insanely attracted to you.
The world is an amazing place.
Every time you have ever had a freakish, desperate craving for paella, someone somewhere was right in the middle of saying "Shit, I accidentally cooked too much paella. Why do I always do this? I hate when things go to waste."
Every time you've had to go from Dallas to Nashville, there was someone else making the same trip that day, with an extra seat.
When I went from Manila (a metropolitan area of 20 million people) to Hong Kong/Macau (15 million) for a conference, there were certainly several people making a mirror trip who would have loved to swap condos, eat from each other's refrigerators, and pay nothing.
There's someone dying to hire someone exactly like you.
Of the 130 million books that have been written, there's one that would blow your mind and change the course of your life more than M. C. Escher's visit to the Alhambra did his.
Every facet of your paradise exists, but you will never make the connections.
We live our lives by chance, picking the major that our local college offers, listening to the music that our friends showed us, and dating the girl we met at the bar, letting most allocations happen by near-chance.
I've probably been a lot more deliberate than most people. I wrote a document classifier that accurately predicts which HN articles I will like. There are layers of automated search and analysis underlying my job hunt, social life, and quest for meaning. But there needs to be much more. For me and for all of us.
I will never hear what would be the most amazing and powerful song I could ever hear. I will never meet my best friend. And that makes me sad.
