Recently, a man (~ aged 65-80) sent me an e-mail in which he told me he was impressed by the system I created (I guess because it automatically sends a personalized e-mail with his order details). He also told me he was interested in informatics (mentioning Excel and C#) but has lost perspective. He seemed upset about that.
I have been thinking how I can help this kind man to regain his perspective in informatics but nothing suitable has crossed my mind so far. That is why I decided to ask HN. What are fun things to study/create/implement/think about? Or what is something he could do to impress his friends with? Or more general, what seems to be a good way to help him regain perspective?
