I hit 51 this week.  Aim for rest of life.  To purchase as little 'stuff'' as I can.  I hope to live a long life and if I do, by the end of it, I would like to leave as I arrived, just me.  Does that sound mad?  It probably does.  I don't mean it to sound hippyish or anything. Stuff you love should surround you then should be loved by others when you no longer do.  Obviously not people!  The de-cluttering quest  continues!!
