Oh dear, I think I was a late developer. I don't remember being particularly good at anything as a child. In junior school, I was quite academic but, once I went to grammar school, I lost interest so drifted along, trying to keep under the radar, although I do remember a lot of detentions so I must have been fairly naughty!
It was only in my late 20's that academia appealed again and I got my degree and post graduate qualifications as a mature student before, belatedly, embarking on my career.
I do hope my grandchildren never ask me that question! I think I shall have to be economical with the truth, as they say.
