A doctor with a ear plug...your thoughts?

Ok well I plan on being a psychiatrist. I'm still in high school and I want to get a ear plug(pretty big one) when I turn 18. I know that is king of taboo to see a medical student with one of those but I really want one and I'm also planning on getting tattoos but I can hide that...not the ear piercing. What do you think and what are your thoughts on tattoos and piercings overall?
