I am a professor of theoretical physics and an author of several books for the general public and a textbook on quantum field theory.
My textbook, Quantum Field Theory in a Nutshell, was published by Princeton University Press.
As much fun as possible! (This could be a nice motto.)
It is often deeper to know why something is true rather than to have a proof that it is true.
