Which is more stressful, being a training specialist or being a salesman?

Compared with the training specialist, the recruiter is under greater pressure because he has to face the pressure of environment and employment, not just by his own efforts. As long as the training specialist arranges his own work, he doesn't need to consider external factors and works hard by himself. Similarly, the pressure of sales is greater than that of training specialists, because sales work is also related to the environment.
