Hi I have a bachelor in mathematics, but I just do not know where to go next. The reason I decided to study mathematics was because I have been a puzzle solver since I learned to read (mathematical puzzles, mechanical puzzles etc). So, I wanted to see how I could make a living using that kind of thinking. I tried physics and chemistry, and in the end, I settled on mathematics. Not all mathematics gives me the kind of joy puzzles do. Functional analysis seems too abstract (however, this may change if I ever get used to the abstractness). For some reason, multivariable calculus just does not feel very satisfying (again, this may just be because I am not very "fluent" in the methods of multivariable calculus). On the flip side, solving problems on projecteuler.net is amazing. Game theory is great. Discovering mathematical biology is one of the greatest things that happened to me in 2013. Complex analysis was fun. I also want to make things (part of the reason is probably that I wasted three semesers in business school before going to a university to study science). It doesn't matter if it is software or machines. So, I am completely stuck. Sometimes I consider mechanical engineering (I only lack fluid mechanics to take a master in mechanical engineering). Other times I consider computer science. I have also, due to mathematical biology, considered biophysics (but, imaging does not appeal to me). If I seem confused... Well, yes, I am. Any suggestions on what I should do next?
