There is an assumption that as we get older we will get wiser, not tue i'm afraid. The rule is we carry on being just as draft, still making plenty of mistakes. It's that we make 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 u do muck things up. Be forgiving and accept that it's all part of that growing older but no wiser routine.
Looking back, we can always see the mistake we made but we fail to see the ones looming up. Wisdom isn't about not making mistakes, but about learning to escape afterwards with our dignity and sanity intact.
When we are young,ageing seems to be something that happens to, well, older peopel. But it happen to us all and we have no choice but to embrace it and roll with it. What ever we do and however we are, the fact is we are going to get older. And this ageing process does seem to speed up as we get older.
