As there are so many fields in physics ranging from relativity of the large and quantum of the small, I just can't decide what field I exactly want to go into. I've tried researching topics such as relativity, quantum theory, elementary particles and string theory which kinda goes into cosmology but every single one seems the offer the exact same awesome experience. I would love it if I could major in every single one of them but it just seems that there's too much in any one field to focus on all of them at the same time. I guess I'm just looking for some guidance as to the benefits of the certain fields such as job demand, subject matter and previous experience with said field. Any physicists out there, share your experiences please :) Thanks for your replies.
