Do you think that you can only get up to 80% of a person for you in a relationship/marriage?

Like basically there can never be 100% because noone is perfect, but if you get close to or at 80%, then you should keep them as a partner.

The 80/20 rule says that you should aim to get around 80% of your needs met in a relationship, and the remaining 20% you should fulfill yourself.
