You should not set your path based on your currently obscure visions. This may sound like a cliché, but you should do whatever is fun to you and makes you motivated. If you are thinking about entering a graduate school, look back on your undergraduate courses, and pick out the subject with which you had the most fun studying – that subject that made you feel like you’ve accomplished something.
Frankly speaking, I do not believe that elites like you should worry so much about financial status. Therefore, do whatever pleases you. Prior to promptly deciding on your path, anticipate how you will feel about your job when you are 30 or 40 years old. If you can wake up every morning, content with your work, I believe that is the most success one can achieve in life.
