I fully agree.
It's probably a hybrid for me. I genuinely connect with the work of medicine, and it is by far and away the most interesting career one can have, in my own humble opinion. I also have a set of personal philosophies which compel me to serve others; I have always done so, and I will continue to do so for the rest of my life - medicine or not.
I don't know if time has made me grumpy (probably, tbh) but I see these 19 and 20 years olds at the institution where I did my post-bac, and they're saying things like "If I don't get into med school, I'll just die! It's all I've ever wanted to do! Since I was 3! I have to do this or else I will just work some minimum wage job for the rest of my life and be forever unhappy!" And I'm like "What on earth are you even talking about?"
I don't think medicine will ever be the be-all-end-all of my life like that. At the end of the day, it will be one important part of who I am, but just one part.
