You have what Sally Hogshead calls "Tourist Indecision": Anxiety resulting
from a sense of being lost or proceeding without clear direction.
Basically indecision causes stress.
Ever taken a Myers-Briggs personality test? I'm a big believer in it.
Check out "What's Your Type of Career?":

Reading that book was a real eye opener for me. It was like someone was reading my thoughts. This book will help you determine what kind of environment you thrive in.
Cheers
