Mathematics: Yes.
A career in mathematics is from a very diverse background and just one of many in this area of profession. Mathematics is used all around in modern industries and being able to work in this field is a very promising job. I would probably go for applied mathematics, able to solve practical problems for the world, give the world a hand. Most mathematicians require a Ph.D., but I'm up for the challenge and want to be able to achieve such goals. As a mathematician, you get not bad pay and it's just amazing how much you can make. This is a job I would probably go on to pursue, since I am a math geek myself and just my "fun zone." I would really enjoy my job as a mathematician and just the fun from it is weighted higher than anything else.
