Medical school is a difficult time, and we all have our doubts. There will always be a pressure or a temptation to quit at moments. I want to encourage anyone considering a career in medicine to stick with it. Many prominent MD youtubers have left the medical field. I want to encourage anyone in the middle to do your best to finish your training before you move on to another field. Really it's only by being a fully trained physician that you will truly know the ins and outs of the profession.
It's ok to have doubts. Let me encourage you to stick with it.
