I'm not under any illusions, I will lead a mediocre life, a middle-of-the-road, adequate, prosaic, lacklustre, tolerable life.
Don't misunderstand me, I believe I'm lucky my life is middling. Were I born in 1 AD, I would be 1 in 170 million, or 1 in 400 million, give or take a few million.
Today, I am 1 in 7.8 billion. To contrast this, my chances at winning the lottery are roughly 1 in 14 million.
Then consider that the odds of my soul/consciousness/whatever inhabiting a body in this particular time as opposed to say 200,000 years ago when the world population was 100,000 to 300,000 give or take a few thousand. That's got to be worth a few hundred lotteries.
"But Moe!" you say, "That's imaginary money!", sure, of course it is, what isn't imaginary? But doesn't it also help us understand why so many people of adequate means are unhappy. Every time you sneeze, 4 babies wail and 2 people leave us for parts unknown (no pun intended).
If you're ambitious, then yes, the grass is always greener, by all means, you do you, hopefully happily, but if you're not, if you are a workaday, unpretentious, middle-of-the-road pedestrian. Then you my friend are in for one amazing mediocre life. Live it well, live it adequately.
