How career frustration is actually the key to career fulfillment

Earlier in my career I was embroiled in an inner conflict.

I felt that I was being underpaid and taken for granted at times. It was difficult to communicate with my boss and deep down I felt unfulfilled in my job.

I was unsure what to do about it all. And I was getting frustrated.

Sometimes I felt angry, impatient, jealous, negative, rebellious, stubborn, and exhausted. Sometimes even vindictive and hostile.
