I wouldn't call it diagnosing. Just suggesting they consider it.

Personally it all sounds very familiar. So familiar I'd admit I'm mildly depressed. But I do still have a pad of good ideas that I add to.

Also very interesting is that yes even with ideas I'm not good at doing them - but the suggestion that their thing might be the enabling others to achieve theirs really sticks out for me. I'm definitely at my best helping others to do better.

All in I'd say it was a good response.
