The biggest thing that scares me is the unknown. Not knowing what's going to happen next.
The second biggest thing would be giving up and not fulfilling my goals in life. This fear ties along with not making my parents proud. Something I really strive for sometimes. Not only do I do things for my benefit, I try to think about whether my parents would approve. Their opinion about certain things in my life is very valuable to me because they know me best and they obviously love me very much.
