How do you measure the success of a night out?

While I was in twenties it was did I spend a night surounded by people I like and by how much I’m hungover next morning. If I was really hungover I probably made some regrettable decisions but who cared.

Nowdays it’s did meet someone influential in my field who will be beneficial in future, made any business deals and ate something nice paired with good wine or did I have fun date with my fiancee
