Ks, no wonder you are proud of your son's enthusiasm and interest in everything.
nightynight - tell that to my husband!
My feelings towards being top of the class are tainted by the knowing the history of my husband and also my best male friend who I knew from the age of 4 years old. My husband was top of his class, early reader (no TV so books and more books from childhood) exceptional singing voice, (his teacher wanted him to try for the Vienna Boys choir). He had a very rocky life in his teens and early twenties and has an ordinary job now that he is reasonably happy in - and he's still an avid reader - for pleasure.
I male friend had a brilliant mind, top of his class again, won an exhibition scholarship to Kings College Cambridge, couldn't cope, became intensly paranoid, couldn't hold down any job and died an alcoholic at the age of 42.
