What would you do if you cannot become a scientist?

I want to be a physicist in any area of physics. The reason is it is an ideal job for me. I love teaching and I love doing research.

I enjoy sharing my knowledge and finding things out. In my mind, physicist = physics educator + physics researcher. Being a physicist can allow me to do both. I am interested in ALL areas of physics. Basically I am a physics geek. So I really hope that i can have the chance to become a physicist one day. But i know that a crucial step is to get a high-quality PhD degree.
