OK...maybe I'm not full timing it right now, but I was for awhile, and 1 thing I've noticed reading this forum (and the old one) and just from my own experiences, was that even though the place you're living in has changed (oftentimes dramatically), you don't change much.
Meaning...I don't have property taxes, my usual monthly bills, and a 9 to 5 job like I used to, but I still have things that I hafta deal with on a daily basis. I've still gotta feed mysself, I've still got (some) bills to pay, and I still need to maintain my home (even though it's now on wheels.)
I still get stressed about the neighbor's rotten kids, and their stereo being too loud. Gridlock still makes me crazy, and sometimes, I still just wanna stay in bed all day. I'm still ME inside, and I've still got ambitions I'd like to accomplish in my lifetime, and things that I'd like to do, but know deep in my heart are not gonna come to fruition. Certain things that drove me crazy in the past....still do, and things I was passionate about, I still am.
However...
The freedom of not having to keep up with my 3rd car and mortgage payments no longer looms over my head. I don't need to worry about if my lawn is getting too tall to upset my neighbors, nor am I worried that I've got this mountain of JUNK in my home and garage that I need to figure out what to do with.
That sunset sure is gorgeous tonight, and I no longer worry that I'm taking too much time to enjoy it, nor does just sitting here by this lake. I now have the time and the freedom to come and go as I please, and if I don't like my sorroundings, I can simply pick up my megar belongings and move on! It's all up to me now.
So, I think that the peace of mind comes from knowing that your life and your time is now fully yours, to enjoy however you please, WITHOUT worrying about the constant overhead of a house, and the belongings in it, and the crappy jobs to maintain it all, is where the stress goes out of your life.
and THAT, to me, is what makes this lifestyle worth more than any of those extravagant possessions can never give back, and that's what makes it worth the sacrifice of giving that all up.
