This may sound dumb, I'm 18 years old and am in second semester of my first year at university. I've been getting great grades so far. I've been introverted most of my life through elementary school and high school and have had few friends. I feel that my introvertness can be a disadvantage if I were to be a dentist. Sometimes, I have trouble communicating with others, and find it hard to carry on a conversation. I like dentistry because I would like to be my own boss, run my own business and help others, but I just feel that I can't do it because of my introvertness. Anyone else feel the same way about themselves? What can I do to solve this?
