Fearing fear

I've cracked...I am officially reading a self-help book. Scary. I know. I always steered clear of that section of Barnes & Noble but for some reason I was drawn to "Feel the Fear and Do It Anyway". I had a discussion with a friend the other day about fear. Fear can come in a lot of different forms. Fear of failure, fear of the unknowing, and something that surprised me while reading this book is the fear of succeeding. I've never really thought of it in those terms. Sometimes it's just as frightening to succeed at something than it would be to fail. I think there are most expectations placed on your shoulders when achieving your goal...the "what's next?" questions is brought up. I've read stories about the depression some people feel after reaching a goal such as receiving a PhD...they're at the top and aren't quite sure what's next.
