I have a problem: I'm a quiet, serious type of guy. I tend not to engage in small talk and don't really have ''friends'' but rather acquaintances. I'm not outgoing. I stay to myself and just mind my own business. I'm really good at one-on-one conversations but tend to stay quiet in groups. Is this fine? I tried to talk more and engage in random conversations but it didn't really work. So now I'm content with the fact I am who I am. Can this type of personality be successful in the medical profession or will it lead to problems down the line?
