For those of you that don’t know me, I read a lot of books. What’s a lot? In a slow year I’ll read 50, and when I’m really into it, I’ll read 70 (and that doesn’t count John Grisham’s books). And I love bookstores. I’m in one right now looking at several books. Three of them have chapters, or subchapters, with some form of the title, “What is strategy?” For a word that is used so frequently and given so much importance, it’s distressing to see how difficult it is to understand. Don’t get me...
