What do you mean "is it important"? Do you mean "Is it something that everybody should do?" or do you mean "If you do it, you should take it seriously."? Because I think it's something, that if you do, you should DEFINITELY take seriously, but it's not something that's for everybody and if you don't do it, or you don't meet anybody you want to do it with, that doesn't matter, you can live a perfectly interesting and fulfilling life as a single person.
I go back so far, I'm in front of me...
