If you are young and troubled and insecure, find your confidence.
This is a message to my former 18 year old self, and to anyone who is lacking in confidence about the future. There is no reason for you to remain so hesitant and frightened, for you are ready to become an adult and to find your way in the world. If you go forward, aiming to do the right things and you are ready to learn at each stage of the way ahead, you are going to be fine.
