There is an assumption that as we get older we will get wiser; not true, I’m afraid. But we can carry on being just as foolish, still making plenty of mistakes. It’s just that we make new ones, different ones. We do learn from experience and may not make the same mistakes again, but there is a whole new pickle jar of fresh ones just lying in wait for us to trip up and fall into. The secret is to accept this and not to beat yourself up when you do make new ones. The Rule really is: Be kind to yourself when you do muck things up. Be forgiving, and accept that it’s all part of that growing older but no wiser routine.
