How can I become a movie critic?

I'm not sure if this sub is the right place to ask questions like this, but from what I've seen on r/movies so far, there's an awesome passion for the art of cinema. I absolutely love movies, and can analyze them for hours. If I were to try to become a "movie critic," how would I be able to do so? What different paths lead to such a career? How much or little does education play into this? Is luck a big part as well?
