In my others stories on problem solving and how to create innovations I introduced many skills to readers. Here are another set of skills—how to solve external and internal problems. That is: the 1st, I classify a problem by asking: what type of problem is it? There are 2 types of problems: external and internal.
External problems (outside problems)—arebeyondmy control.
Internal problems (inside problems)—areundermy control.
To visualize how and when to use this set of skills, in my story, as usually, I gave some real life examples of problems that readers are familiar and could relate to such problems.
