Not sure I understand your question.

It's not limited to surgeons. I only know a few doctors and was responding to another comment on surgeons.
Many business owners also fail. In fact, majority of those who started business has likely failed. A few of my friends who ventured into business has failed (corporate gift service, team building/event company, etc) We only hear the success feel good stories online.

That guy I referred to earning RM200k monthly.. He has worked as a doctor for >20 years before getting sub-specialized. Now reaping the rewards at late 40s but still working non-stop. No time to spend with fam and kids.
