Frustration is seen as a negative, but frustration, like pain, serves as an important corrective. When we experience pain, we alter our actions (if we touch the hot coal, we withdraw our hand). However, when we experience frustration, we tend to “wallow” in the condition.
Frustration is an indication that something is wrong. Thinking should be fluid. One must be careful not to accept, and thus get trapped, within a condition of perpetual frustration. Sometimes the answer to the question is only this: Did I ask the right question? This leads to another: What is the right question?
