What is it? "It" is not as simple as it may seem. Frequently, "it" means different things to different people. When "it" is an issue or a problem is "it" defined in a way everyone can understand? When "it" is a behavior (e.g. I can't help it), "it" is often not a single factor but rather a complex combination of a multitude of different things.
To succeed in the future, we must all do a better job of understanding what "it"; why "it" is important; how and when "it" will get done; and who will get "it" done.
To do anyhing less just makes a mess of it.
