To overcome that situation, as a proactive, it is essential to find and do something beyond your daywork that fulfills your inner feeling. For example, some of my known contacts and friends are engaged in activities that are not related to their current profession. When interacting with them, I realized they are feeling more fulfillment in their extra activities beyond work like
One person engages himself in reading books after his office hours and weekends
One medical practitioner engage himself in conducting free medical camps / educating people on health on every Wednesday
One person is preparing himself for marathon participation
One person opens up his library after office hour for public and for mentoring the needy people
The point is that you need to find a way to get a sense of fulfillment when the work circumstance does not provide. The only thing you should ensure is that the path must be more meaningful to you, and it should not affect your regular work, family, the community at large. The choice of feeling fulfillment is with you only!
