37% rule

> Estimate how many people you’re likely to date in your life, dump the first 37% but keep a photo of your favourite on your bedside table. Then, marry the first one after that who beats your sweetheart! Of course, every rule has exceptions and sometimes you get an offer that’s too good to refuse, 37% or not. Sometimes, mathematics doesn’t have all the answers!

> Using this process, we find that we can be successful in selecting the best from a group of N by letting approximately 37% of the available positions go by, then selecting the first choice better than any seen before about 37% of the time. And this is true no matter how large N is! This is a strikingly high probability.
