My honest answer is there is no single answer I can think of that is the greatest it can answer. It's not an end. It's an ongoing process that is always improving if we as a field continue to practice and research it in a scientific and ethical manner, just as one could never expect to 100% rid a society of crime, invent a 100% efficient machine, or find an equation that solves everything, but what's more important is we keep our ideals to always go in those directions. Whenever we figure out the next step and how to make it, we'll find ourselves with our next set of problems. I'm more interested in being part of the never-ending endeavor.
From that, the most important question for myself is how will I deal with this given the complexities of life and balancing it with the hope of being a happy and whole person?
And then the layperson stereotype belief, “I’m going into psychiatry to try and better understand my own pathology.”
I've seen actually several people go into this field for that reason. Students tend to pick the field that treated a specific disorder they or someone they loved suffered from in a manner that significantly affected that person.
I don't think this will make for a bad resident. I do believe this may even further embolden several to fuel their passion to help others and make them more sensitive in regards to empathy.
Unfortunately, however, I have seen some residents with some very significant pathology to the degree where it could not be excused. One particular resident I saw make recurrent and false allegations that several other residents and attendings raped her, and it seemed to be due to histrionic PD because when asked if she wanted the police involved, she always insisted no (among several other things such as one day showing up to work wearing a see-through shirt you expect someone to wear if they wanted to give out hook-up signal at a club). After the third false accusation, and several several practice errors (E.g. she kept over-medicating patients without informing the attending including Depakote to a pregnant woman) the program I was in kicked her out.
I later found out she got into another program, happened to get into a discussion with the chief there, and that chief found out what program I was in, told me the path of destruction that same resident did there, again claiming she was raped and blaming several attendings of both sexes of doing that.
