Recently I have been a tad depressed. Whenever I look up how to become a professor if physics I come across discouraging things. Everyone seems to say that my dream of getting a job in academia is like a dream of playing in the olympics. Unfortunately, I cannot see myself being anything but a physicist, or some sort of scientist. Are my dreams realistic? Also, I keep hearing that there are few jobs in the area of physics, is this likely to change in the next decade? I am afraid of wasting my time in graduate school if this is really unlikely.
