Amandastan, Im happy that your new life suits you...
...but not to put a downer on things, it can come back to bite your ass later in life. I've got a decade and a bit on you. I've lived my life in a very casual way, going where the wind took me, not to the extent you did, but I never 'settled down' to use an expression I hate. I don't regret it much, I've had some fantastic times that my more 'settled' pals will never experience. To be fair, I did 'join the workforce' for a while and looked forward to a bright future...that secure, leading-to-better-things existence a few years ago is now gone thanks to UK politics and layoffs (but that's another debate) and now I'm the wrong side of 40, hard-up, making less money than I was in the 90's and just trying to keep a roof over my head...
Again, I regret not much! Some amazing times! But 'why would anyone work one steady job again'? A comfortable lifestyle is something you might want to think about a few years from now...
But, heck, enjoy it while it lasts!
