This classic has sold 15 million copies and was the first self-development book I read back in the day (1995 to be precise). In this Note, we'll take a quick look at all 7 Habits—from being proactive (huge!) to beginning with the end in mind, putting first things first, thinking win/win, seeking first to understand, synergizing and sharpening the saw. Lots of goodness here to help us develop our character to create our ideal lives as we most fully give ourselves to the world.
