It seems to me like we repeatedly, as a society, bear the cost of imparting (often simple) life lessons like this to people, at the expense of others. Coders often learn a sense of architecture and conventions by making mistakes at their early coding gigs, and new managers make old management mistakes too, and I think this factor has a very real cost in terms of failed projects that die or coast along due to difficulties rather than taking off. That's not to say it's easy, I'm sure if you told this guy to lighten up and smile more, he probably would have resented the advice at the time, but is there no way we can impart on-the-job learning at our learning institutions?
