Simplicity
I have been reading a great deal lately about simplifying life. The library got me started actually by offering classes on voluntary simplicity. The book Graceful Simplicity captured the spirit of the movement for me in this quote "Just Enough is Plenty, every person lives within a household and the household has its economic needs - but the point is to attain only what is sufficient to enable one to turn away from money-getting and undertake the real activities of life"
Like many philosophical ideas, for me, the longer you think about them the less you understand, but perhaps Aristotle summed it up best in the goods of the soul...fortitude, temperance, justice and wisdom.
Perhaps it's just reaching middle age, but being released from all the getting, collecting and having is becoming pure joy. Of course from the looks of eBay, I'm standing alone on this one.
