I came to Mr. Covey and his seven habits late. I still think his book one of the best things ever written for people in modern organizations, and I am amazed both that not everyone in business and academia has read it and that so much of the other stuff written in organizational behavior is just faintly-disguised imitation of Covey.
So I thought of Covey when I saw these dried fish in Estonia last month. You sharpen the axe in winter, but you dry the fish in summer — to have something to eat in the winter. Always provident, Estonians have been following Covey since before he was born.
