Planning is a managerial term. It’s working material is solved problems. It’s end is a tamed reality.
Solving is a creative term. It’s working material is an untamed reality. It’s end? There is none.
Our habits and thought patterns can be cued by triggers in the words we use. Do you plan or do you solve? “Plan” and “solve” may look and feel similar but behind the doors of each word are alternate realities.
