Hello physicsforums, I am a 28 year-old undergrad physics student from a decent university in Turkey and I will be graduating this summer. My undergrad education has been a bit problematic at first so it took me this long to graduate but I achieved a very good GPA and I am currently looking at possible master's programs in Germany. I want to continue my education in physics but the problem is my restricted electives(concentration courses in physics) are all over the place and I can't seem to figure out what field I want to study. I am terrible at making decisions and I think this trait of mine will cost me some day. Things can change but after my master's I want to work in industry so right now I don't plan on pursuing an academic career. For this reason, I took some electives in optical-electronics but I didn't like it much. Then some particle physics which I enjoyed more but I'm worried about job opportunities in that area. During my last semester I will be working with my computational methods professor on graphene in B-field which I will be looking into. Thing is I have no background at all in solid state physics so that scares me a little bit. My question is; what are some possible ways I can figure out which field suits me best? Since I will be writing my SOP soon, I will probably make up many things regarding "career goals" in the statement. I attend as many seminars as I can but they are usually very basic so they don't give me enough idea to decide. Right now I'm thinking that my best bet is condensed matter/solid state as career opportunities go but I am probably being very naive in thinking that way. Any help is very much appreciated.
