Not to be argumentative, but there's a reason the process isn't easy, and ultimately the pressure comes from the individual themselves, not the professor or institution (not one of my professors ever told me I was obligated to work myself ragged, they just assigned the work and graded what I chose to submit -- it was all on me as to how much work I chose to put in to get an end result I found satisfactory.) Just like with anything worthwhile, it involves a considerable amount of work to achieve the end goal, and the process culls out those who may not be able to adequately perform the job duties that go with the respective career. I would love a doctor's salary, but I'm not nearly motivated enough to pursue that degree because I am much too lazy to put in the work it requires -- imagine what a terrible doctor I would be if getting credentialed were that easy...
The bottom line is that you don't have to endure any mental anguish to have a career and live your life, there are plenty of paths out there that are happily and successfully followed by those who don't wish to endure the rigors that go along with pursuing an advanced degree.
