I’m an incoming internal medicine PGY1 with a strong interest in cardiology, particularly EP.
I wanted to ask those further along in training:
What advice would you give your younger self during intern year and residency?
What are things you would strongly recommend doing, and what mistakes would you avoid ?
I would sincerely appreciate any insights or perspectives from those who have gone through the process
Thank you
