In time, all great managers discover the wisdom of profits.  Profits are the premiums paid for the performance of promises.  Real profits are not a function of predatory speculation or buying low and selling high.  Real profits of course are the result of adding value.  In fact, it is the same lesson we learned from the late great Viktor Frankl when he talks about success being like happiness.

For success, like happiness, cannot be pursued; it must ensue, and it only does so as the unintended side effect of one’s personal dedication to a cause greater than oneself or as the by-product of one’s surrender to a person other than oneself. Happiness must happen, and the same holds for success: you have to let it happen by not caring about it. I want you to listen to what your conscience commands you to do and go on to carry it out to the best of your knowledge. Then you will live to see that in the long-run--in the long-run, I say!--success will follow you precisely because you had forgotten to think about it.
