From a certain point on, every profession requires something beyond mere convenience in order to be carried out properly. This is usually the case when novelty disappears from the routine, which becomes the execution of tasks already carried out the day before. Then, if there is no motivator beyond what one gets out of doing them, if one does not derive some satisfaction from the daily exercise itself, the job becomes unbearable, the exercise becomes tedious, distressing, torturous. So it seems that the dissatisfied person has to choose between two things: abandon it or succumb to it. Therefore, it is not possible to give other advice than that a profession should be chosen above all with a view to the satisfaction that can be derived from it: in the end, everything else that can be obtained from it will be linked to the existence of this possibility, or not.
