How Much Incentives Are There for Doctors to Increase Their Knowledge?

I wonder how much incentive there is to increase your knowledge for a doctor. Is it the case that you're basically just waiting in line to rise to the ranks of being a doctor? I'm thinking about like let's say a moderate use of flash goods okay not a the heaviest super memo neuro review whatever. Do they have better business skills than public doctors skill wise? The more specialized your field is the more counterintuitive almost the more space transportation could help you advance your career.
