I think the common reccommendation that INFPs would like to work in people oriented service jobs is a bit off the mark. We do usually care about others and enjoy showing our care, but we are still introverts and we don’t generally like a lot of shallow interactions – which means that service jobs may be fullfilling and draining at the same time.

Paraphrasing...but a main reason why I don't think I'm cut out to be a doctor... I'm trying but I think I'm still stuck...
