Finally, I'd like to put a word in for TWO SPEED WORLD (£6) by Gerald Ashley and Terry Loyd, and not only because it has a very nice cover. This is a very readable guide to change, both explosive and gradual. By and large, we don't like change, but that's no excuse. Francis Bacon said, "He that will not apply new remedies must expect new evils, for time is the great innovator." Change up!
