I am 15 and in high school and recently there has been a big push in our school system to decide on your career now. For the past 7 years I have had it in my mind to become a nuclear physicist. Now, however, I can not decide on what physics field to go into. I can not choose between nuclear, astro or theoretical physics. In the past I have read over career descriptions but what would the career actually be like? Words are often forged to play on the beliefs of others and I wish to know what really occurs at the job sites.
