Simple? What Does That Even Mean?!

I keep coming back to the basic question of simplicity: What does it actually mean to seek simplicity, and to have a lifestyle of which simplicity is a hallmark or a major component? Different people have different ideas regarding what it means to be simple. A few major themes I've noted in reading and researching on this topic:

• Frugal. Many people equate simplicity with living in such a way as to keep from spending much money. This is not a bad goal, to be sure, but reducing a lifestyle principle to pinching pennies seems rather extreme.
• "Green". This touches a nerve for me, because of all the many things that really irritate me (and believe me, there are a lot--just ask my family), one thing that truly galls me is a catchphrase-driven bandwagon. While I support sustainability, eco-friendly practices and products, and the whole shebang, I really dislike the fact that suddenly in the past few years, everybody has been trying way too hard to fit into this mold, and it shows, because terms like "green" and "eco-"anything are so overused that they are meaningless. Again, this concept constitutes a more-than-worthy goal, but the useful forest has gotten lost in the propaganda trees (which we should all hug now, right?).
• Back to Nature. Grow your own food, store it, be as self-sufficient as possible. [In fact, "Self-Sufficiency" is probably a better label than "Back to Nature". Oh well.] There is a lot to like about this sort of idea. It is similar to being "green", yet somehow less trendy and yuppie. However, this lifestyle is not practical or even possible for many of us.
• Food-Focused. Many people are re-examining what is in our food, how it is produced, and how it gets from its place of production to our tables. This has led to a largely grassroots movement to turn ever more toward local produce and goods, preferably responsibly grown, and, if we're lucky, even organic! Yet again, great idea here, and this one in particular lends itself to being practiced in moderation. However, I might just get a craving for a guava, and then what am I going to do?!
• Reduction. This is good for nearly all of us: Getting rid of not only excess possessions, but also excess complications in life. Simplifying routines, processes, habits, AND our stuff. Really, I just love the idea of tossing out both physical AND emotional baggage.
• Mixed Bag. Maybe the true key to living a realistically simple life, without creating excess stress by attempting to conform to more extreme views on simplicity itself (ironic, no?), is to take elements from differing ideas on simplicity and adapt them as best suits one's own life and style. Buffet-style. Smorgasbord. Mix-and-match. Pick your analogy.
