A doctor who has passive regrets on his life choices and wonders on the inside whether he or she had what it took to start his or her own business. They makes it a priority to take the opportunity to pitch patients who work in software (regardless of what company they work for) in between his or her diagnosis and sometimes at dinner parties.
I stopped going to Dr. Jacobson who is an MD Daydreamer. He always pitches me his idea for canine heart monitors that sends out tweets once a day.
