<p>You have got to decide now what you want to do with your life. If you want to become a Theoretical Physicist I recommend going to a decent college and majoring in Physics. Work your ass off and get into a top tier graduate program like MITs or Stanfords. Then start focusing your research and studies on space physics and such. Go on to earn a Masters degree. Theoretical Physicists get a PhD and then teach at a well known science focused university. The university in turn also funds their research.</p>
<p>If you really love physics and this is your passion or dream, I say go for it. But you will need to decide whether you truly want to devote the next 10 years of your life to studying incredibly hard and spending most of your career not getting paid what you deserve. People do these things not because they are easy but because they are hard and they want to be at the forefront of discovery.</p>
