All the good things that have happened in my career have been because the people around me have been amazingly good.
Find those people, and stick with them - they will take you to places that cannot reach by yourself.
This also means you need to be friends with people and maintain those friendships.
Also, if you ever find yourself feeling like the "smartest in the room" it's time to start worrying. You are not going to learn anything in that situation unless you are a very special kind of person.
