I am a little late in weighing in on this, but my first reaction is "be careful". And could there be something "stoic" about being frugal -- that it leads to the elevation of a type of virtue -- and the perfection of "frugality"?
The definition of frugality on the internet:
fru·gal·i·ty
/fro͞oˈɡalədē/
noun
the quality of being economical with money or food; thriftiness.
"he scorned the finer things in life and valued frugality and simplicity"
synonyms: thriftiness, carefulness, scrimping and saving, conservation, good management, caution, prudence, providence, canniness, abstemiousness, abstinence, austerity, asceticism, self-discipline, restraint, moderation, puritanism, monasticism, monkishness, miserliness, meanness, parsimoniousness, niggardliness, close-fistedness, tight-fistedness, tightness, stinginess, sparingness
Note that the definition includes "asceticism" as a synonym.
I would say that it is important to think of yourself as possessing prudence as a tool for making good choices, rather than being "frugal". There aren't any hard and fast rules for a pleasurable and pleasant life, and we judge each situation uniquely according to our given resources.
Looked up the definition of "prudence":

LOL...frugality is a synonym
