I listed all the bad habits I wouldn't adopt. I think most of them still apply. Not sure about not believing everything was better in the old days. With the British economy on the skids and world war three in the offing things look pretty grim right now. Anyhow this was the list:
I refuse to moan and groan.
I refuse to become a grumpy old man.
I refuse to let the world's problems get me down.
I refuse to make mountains out of molehills.
I refuse to turn petty irritations into causes célèbres.
I refuse to complain about my bodily deficiencies.
I refuse to denigrate other people's lives.
I refuse to tell other people what to do.*
I refuse to rant and rave.
I refuse to demonise young people.
I refuse to be cynical.
I refuse to be paranoid.
I refuse to see the worst in people.
I refuse to be nostalgic.
I refuse to believe everything was better in the old days.
I refuse to think that I know best.
I refuse to think life's conspiring against me.
I refuse to be offended by bad manners.
I refuse to be offended.
I refuse to over-react.
