The older you get, the less you will care about being normal. I'm not saying this is easy. Sure, the world is full of people who will might look down on you or think less of you, or underestimate your potential because of a stutter or your race or any number of reasons that are mostly beyond your control. Prove those people wrong. They're best avoided anyways. Focus on getting really good at the things you care about the most, and focus on taking care of the people you care about the most. Pour all your energy into those two things and before long, you'll probably long for loneliness.
