The maxim ‘Change what you can, accept what you can’t change, and have the wisdom to know the difference’ is hardly a new one. So, what is it that makes so many of us ‘do the same thing over and over again, expecting a different result’? Could it be that we were taught ‘if at first you don’t succeed, try, try, try again’?
It would be good to find a novel, elegant way of expressing the frustration of feeling that no matter how hard you try to improve the life of a loved one, there will be times when there is no ‘you-shaped’ solution to apply in order to achieve that goal.

I often thought thought that ‘accept what you can’t change’ is a bit of a copout: how can you know that you can’t change something if you don’t keep trying?
One of my recent maxims is to ‘appreciate the little things’: if one can manage to glimpse the shadow of a smile, or feel the squeeze of a hand, or hear a kind word, that can be enough. Oh, and to appreciate that one is doing one’s best. Xx
I think the emphasis is on changing what you can and not obsessing about the things you can’t change (e.g. other people!).😁
