Delicious question, (@olman)! I, for one, believe change IS possible––at ANY age. I'm 80 and I continue to work on change. Let me say, however, I'm not a New Ager, nor do I cotton to psycho-babble. With that disclaimer, I'm all rah-rah! for change. Just a few days ago, my partner suggested I read a New Yorker article on perfectionism. I harumphed as I often do, mumbling 'Okay, okay I'll read it. Well, I read the article, got to the end, set the magazine down, and right away thought, 'Holy sh*t! Maybe perfectionism's been my problem all along? Maybe perfectionism's the reason I've never completed X, Y, and Z? Possible?' I refuse to steer us into a discussion about perfectionism: Does it exist? Is it harmful? Is it a myth? Or is perfectionism (assuming it exists) actually a help to living happily and effectively–– not a hindrance, after all? I bring up perfectionism only because the possibility that perfectionism has been a lodestone in my life for all these decades is only too real. At 80, I'm going to investigate perfectionism and, if I think it necessary, do something about it. The poet Rilke knew what he was talking about when he said, ' … for here there is no place/that does not see you. You must change your life.' And with that, I'll shut up. I've a few other things I must do with what remains of this dwindling day. However, I hope others will continue this discussion. I'd like to add the occasional two cents. My best wishes, @olman.
