In the previous post we highlighted that the most difficult decisions you will ever make are the ones where you decide NOT to move forward. By focusing your resources and energy on narrowly you can achieve number of benefits and get higher return on your investment of time, money or effort. We mentioned how Apple has succeeded to become the most valuable company in the U.S. by applying this principle, while GM had floundered by spreading resources over multiple brands with lot of overlaps.
You should use this approach in decision making every step of the way. If you take a step back and think about the decision in terms of cost vs. benefit of the current choice and evaluate it against alternatives you can improve the odds of making the right choice. You can use this principle in number of different areas as shown below.
