[Question] Concerning my Role in the film.

So, I've just entered this big open world of film-making. I've acquired a decent camera, a T6i, on the recommendation that its a good camera to learn with. But, as I was discussing my new film idea with my friend over lunch, he asked me if I would be adding special effects to the film as well.

So, I was wondering, if I should invest time into learning to use a effects software like After Effects, or if I should focus on Directing and Filming the movies as I'd pictured them, and then hire someone later to put effects in, as needed?

Thank you for your time.
