She has a nice salary, as well as company performance bonuses. She has a company car, with unlimited personal use when not used for work. She is unstimulated and does not wish to continue with this position and would rather work harder but be challenged. I told her to get a hobby or join a course or something but not give up such great work conditions especially since her lenient schedule would allow extra curricular activities. In summary, as a person goes about his or her work, lack of challenge can create a course to burnout.
Most people can add zest to their job by searching around for new elements to learn.
Focus on the things that you like but are not good at. Always look to adding new elements to stay challenged. Ideally, work should be fulfilling.
