In his delightful best-selling book, Thinking, Fast and Slow, Daniel Kahneman, a Nobel prize-winning economist, writes about the many unexpected ways that our brains think. Two of these relate to the Law of Small Numbers, and the Anchoring Effect.
In his book, The Power of Habit, Charles Duhigg describes a framework of four steps through which a bad habit can be changed. Duhigg cautions that there is no single solution, but rather that analysis and experimentation within a general framework will be effective in many cases. Using this approach, changing some habits will prove very easy while other habits will require more effort, and others still may become an ongoing process.
For many people, there is more to do than time available to do it. Acting effectively means being able to decide which activities should be done before other activities. Stephen Covey, in his best-selling book, The 7 Habits of Highly Effective People, provides a method for evaluating the priorities of activities by dividing them into the urgent and the not urgent, as well as the important and the unimportant. When activities are grouped by their importance as well as their urgency, the result is a matrix with four quadrants: important and urgent; important and not urgent; urgent but not important; and neither urgent nor important.
