My answer to Why do so many people hate their jobs?
Answer by Ken Larson:
I am convinced the observation you have made is due to a mismatch of job with personal value system. I spent 20 years in the Military Industrial Complex learning to hate my job.
Our existence and our mental universe are driven by factors that we as individuals inherit through the gene pool, as enhanced by our experiences in life. In short we are most at peace when we are in sync with the personal value system that has evolved as a result of the above factors and when we are permitted to pursue our values in our personal and professional endeavors.If we cannot achieve that harmony we will seek change.
It seems at the 15 year point (mid career) one should decide whether one is content continuing in a current line of work or make a change to a field that better fits ones value system.
That is where the trade off must occur between all the baggage accumulated (economic and otherwise) and the continued aggravation.
I waited too long before switching to small business consulting and ultimately volunteer work. I advise younger people to look closely at their mid-career milestone.
