You shouldn't. There are fast thinkers and slow thinkers. I consider myself a fast thinker and let my intuition flow through a problem. Then I try to solve it rigorously. My SO is a slow thinker though with an extremely different mindset, we learn physics together. This incompatibility really shows when we are talking about physics, I rely on my intuition a lot, then she asks the hardest questions ever about the most "intuitively simple" things.
