As I near my 50th birthday the one theme that has been loud and clear in the last decade is that the only accumulating I find of value is in experience and perhaps love is the greatest of these. There is perhaps no greater joy than in shared experience, and later, the memories of them.
I know many people who accumulate more and more each year and perhaps it is a futile effort to slow down the rotational force around the sun, but give me a lifetime of memories and someone to share them with and I would have my nirvana.
