How do you view a man who is a workaholic? And what qualifies as a workaholic?

I asking because I am stepping away from dating in my late 20s to pursue being a doctor. I have one more year left in med school and then residency. Lately I havent been feeling dating, and I really want to work on being a doctor. Currently in family medicine and I absolutely love working with a diverse group of patients. However, I am extremely lonely and think about getting married.

My life consists of working from 7:30-3 and then studying until 10pm. I only go out for a social event Friday night.

In the event, I change my mind, how attractive is this in dating?
