I presume hale is just mocking the current students who would come in and say that.
I'm one of them. I wish I had realized how all consuming medicine is and that because of how it is it's not really just a job - it changes your whole life style. I really wasn't career driven enough for medicine. I'm not unhappy I just realize there are a million things I would have been just as happy with minus the sacrifice.
As far as things I wish I'd known...I wish I had trusted the curriculum more. I gave up on glass and started studying for boards VERY early but really didn't have enough discipline. Took a very long vacation for most of 2nd year skating by and passing tests which made my boards that year particularly painful.
I wish I'd done more for me. I didn't study that much but I mostly tried to pretend I was. I wish I'd gone to the gym EVERYDAY and made it a lifestyle long ago so it would easily continue in residency.
I wish I'd stuck around more 3rd year. I had great residents who let me go home when the work was over but I feel like if I'd stuck around I may have gotten more procedures.
Other than that I'm pretty happy with how things turned out, my board scores were fine, I ended up gettig involved I great extracurriculars that really made me stand out as an applicant and helped me get amazing letters. And I got my first choice in the match, so I guess everything worked out fine in the end.
Also, I am so glad I used less vacation 3rd and 4th year And got more time at the end. I am done with med school and still have 10 weeks to do whatever I want before residency starts.
