“A man rarely succeeds at anything unless he has fun doing it.”
—Dale Carnegie, How to Win Friends and Influence People, a book I’m shocked not to have read yet and that ought to be mandatory reading for academics, who are very bad at applying its lessons. Not everything in the book I buy but overall it is much more interesting than I expected and much better written. Note that this is the pre-1981 version, which means some references to gangsters and “popular” figures are dated, but as often happens with very old books it is revealing about its own time in ways not intended by its author.
I often see the point quoted above said regarding writing, coding, and any number of other activities. Yet I rarely see it said regarding, say, tax law, or accounting, or proctology, or garbage hauling.
