…if, somewhere out there, is an even better SO for you?
For me, I seriously doubt it. My wife and I seem to be made for each other.
…if the best (book, album, movie, tv show) you’ll ever (see, watch, read) is out there and you’ll never know?
I like to think that things I like will draw me to them. However, I do get an occasional surprise and get into a new author or group or song, etc.
