This is a powerful statement. Creative problem solving is a process of asking advancing questions. Yet too many people stop when they don’t hear an answer that they like. Or they stop when they are frustrated. But, the only way to learn is to ask probing questions. You might ask those questions of others or yourself.
The more questions you ask the better you will become at it. Not all questions are good questions and often it is a matter of the right question at the right time. Listen to the answers especially when you don’t like them.
