In principal, I agree with most of these thoughts. I tend to be quite frugal myself.

But, I aim for larger lifestyle changes that let me keep smaller luxuries because they save me so much. For example, I hunted for a career that I could always do from home so that way I could save on commute time, work wardrobe, food, and overall stress.

I spend on wellness (yoga, healthy food, vitamins) in the hopes that I won't have to spend money on expensive medicines in the future.

I cook nearly all of my meals as opposed to eating out. That way my husband and I can take small trips every once in awhile.

I live in an inexpensive area and drive an old car. That lets me buy things like musical instruments (I have two, violin and mandolin), cultural outings, and other leisure activities.

I care less about the small calculations, and more about what adds up to bigger picture happiness and fulfillment.
