And what I noted, since the really big ideas carry 95 percent of the freight, it wasn’t at all that hard for me to pick up all the big ideas and all the big disciplines and make them a standard part of my mental routines. Once you have the ideas, of course, they are no good if you don’t practice. You don’t practice, you lose it.

The root of the problem is the failure to distinguish between operational effectiveness and strategy.
