This is strange advice? I would assume becoming a doctor is hard, extremely expensive, takes a long time and not something you should go into because ‘you see your friends making 6 figures’
Stange advice indeed. It will take years to become a doctor and you will be over 40 and starting with no experience.
My daughter went to med school right out of college and is just now doing her last year of fellowship in her specialty. Next year, she'll be earning much more than I do. It was expensive, but not enormously so compared to what one will earn.
