Like srrs said, I do not believe for one minute that living frugally is suffering!
I have been in a position where I could have purchased a car or expensive clothing, and eaten in expensive restaurants, and so on, but personally, I think of those things as a waste of money. I have other priorities which mean more to me.
Also when I got rid of most of my stuff ... you would not believe the weight that was lifted off of me! I struggled with the idea of giving stuff up ... almost like giving away a security blanket or something .... but after I did, I felt so incredibly FREE!
