You can apply this to find your best potential life partner.
Suppose you expect to meet and evaluate 10 partners over the next 10 years, the limit you set yourself to get married.
Say you date each of them for 1 year.
- You should date and reject the first 3.7 partners.
- After these 3.7, you select the next partner who is better than all the previous 3.7.
This strategy maximizes the probability of choosing the best partner out of the total you will meet. Statistically, it gives you a roughly 37% chance of ending up with the best partner.
