I know everyone's had a big fear during their academic careers; mine currently is the fear of which field to take. I'm a current 2nd year physics major at the University of California, Davis and I am having doubts about physics being the right path for me. I do well in both physics and mathematics field but I don't know if I want to be an engineer, physicist, or something completely different but reliant on mathematics and physics. Tell me your biggest academic fear as you went through life? Did you overcome it? Is there any helpful advice you can give to me or anyone that comments on this post.
