Whether your preferred method is drawing, writing, or acting; working with clay, numbers, or food; raising crops, children, or awareness; building cars, homes, or statues–express yourself however you need to.  No one else can do it for you.  You are the only person who can tell the world about you.  Expressing yourself sincerely and from the heart is not a selfish act.  Yes, you will learn about yourself.  But through your genuine expression, we all learn more about ourselves.
