I once sat down and listed everything I wanted to do that don't really require other people. Not like "watch this TV show", but REALLY want to do. Learning some topics, traveling to certain places, some software projects, etc.<p>My list is very, very, VERY long (and includes some long term things), and I'd have to live a few hundred years to do it all. That's if I had no social life whatsoever. I took several sabbaticals (including a 2 years one), long vacations, etc. I can't even dent the list.<p>Ive been married for years and I'm very happy, mainly my wife is absolutely awesome, but even before meeting her I did just fine for almost a decade alone (I lived alone and didn't really go out to social events. By choice. Because of that long list. Too much I want to do!).<p>Now we have a lot of mutual friends, go out, lots of events, etc. But when I'm thinking of vacations, all I want to do is stay home with headphones on for 2 weeks without anyone talking to me. I could easily do it for years: I have before. If something was to happen and I ended up single, I'd probably just do that until I'm too old to take care of myself.
