@mjbryant , rather than approaching this like a debate and gathering data to support your current preference, why not have a real conversation with your parents. Really listen to them. Are they worried about job prospects? Money? Do they understand your ambivalence about your career goals? Have you not articulated that because you don’t want to disappoint them? Don’t go into it with the goal of convincing them to your point of view, but to really understand where they are coming from.
This is an interesting time in a parent child relationship. Parents often don’t share lots of their worries or concerns with their kids in order to protect them. Kids often don’t share things with their parents so as not to disappoint or anger them. Getting to a point where you can have these conversations, where you really listen to each other, will make everyone more trusting of each other.
I am a parent and am much more comfortable with my kid’s decisions now than I used to be because I trust he has heard my concerns and I in turn trust his ability to think things through and ultimately, his judgment. It has taken a while to communicate as adults with each other. You are at the beginning of that but can really play a good foundation in how you deal with this situation.
