All I can say is WOW you are truly living like no one else!
You are walking, living proof that we all can live on less if we put our mines to it.
It's funny I always considered DH & my lifestyle frugal but I really didn't know what frugal truly was till I started reading forums like DS & such.
I think that people whether they have plenty of funds or they have none in todays economy are smart to adopt frugal ways as none of us really know what tomorrow will bring! As a recent widow I have been going over my finances with a fine toothcomb & I am lucky that my DH did the right things & I'll be ok as long as I continue on living with a frugal mine set!
Since I'll be 60yrs old in 10days & stopped working when I was 49 to become DH's 24/7 caregiver I'm so thankful that it looks like I won't have to start job hunting if I behave myself financially. Not that if I had to it would be the end of the world but it just goes to prove that adopting a frugal livestyle has lots of benefits.
Keep up the good work & I hope you have the best vacation ever you have more then earned it!
