The mere answer to this would be that our decisions towards career will make a huge difference in our quality of life as we tend to spend more time at work or we are indulged in thought processes related to work which affect our mental or physical health directly or indirectly. Moreover the profession we choose reflects our personality. Having to concentrate for long periods on tasks you find mundane, repetitive, or unsatisfying can cause high levels of stress. This could be applicable to all of us here. The success which one face in their respective career is only due to the commitment and passion of the individual towards the job, so stop and think if you are moving forward in the right direction.
