I worked with this accountant once, more like a chief council kind of guy. He was about 70 with bulging eyes and a powerful look. At meetings he wouldn't say much. However, at a key point, he would spell out these one-liners that got all of us grasping for an answer. Classic grey-haired man, right? Yep... He was that kind of guy. Quick little quips about what we were planning that boiled us in business meditation (in some cases we actually abandoned our ideas). I wouldn't say the approach was that genius, but it did teach me something. Many times the best commentary or insight comes in small packages. It is the very act of simplicity of action/thought. One might call it thinking before one speaks.
