Physicist: If you assume that there’s one person “out there” for you, and you share a deep connection, then go with that.
If you don’t believe in the “deep connection” part, then you’re shit out of luck.
The question I can answer is: “Of N (ladies and/or gentlemen, hereafter “peeps”), how do I find the best (for me)?”. This question is now essentially the “Secretary Problem“, which happily has an ideal solution.
1) Get N Peeps.
2) Date N/e of them (e=2.718281…).
3) Continuing dating, but the first Peep you meet who’s better than all of the first N/e Peeps, you marry.
4) Stop dating. This is arguably the most important step.
This procedure has a success rate of about 37% (1/e). Good luck out there cats and kittens!
