"You should have a strategic asset allocation mix that assumes that you don't know what the future is going to hold."

What is the manager's job? It is to direct the resources and the efforts of the business toward opportunities for economically significant results. This sounds trite - and it is. But every analysis of actual allocation of resources and efforts in business that I have ever seen or made showed clearly that the bulk of time, work, attention, and money first goes to problems rather than to opportunities, and, secondly, to areas where even extraordinarily successful performance will have minimal impact on results.
