David's Time With Peter F. Drucker 2020.4.30 The first policy——and the foundation for all the others——is to abandon yesterday. The first need is to free resources from being committed to maintaining what no longer contributes to performance, and no longer prodeces results. In fact, it is not possible to create tomorrow unless one first sloughs off yesterday. To maintain yesterday is always difficult and extremely time-consuming. To maintain yesterday therefore always commits the institution's scarcest and most valuable resources——and above all, its ablest people——always runs into unexpected difficulties. It therefore always demands leadership by people of high and proven ability. And if these people are committed to maintaining yesterday, they are simply not available to create tomorrow. ——《Management Challenges for the 21st Century · Chapter3》(Peter F.Drucker,1999)
