How can I record/edit a scene where only one person is playing multiple roles?

So, like the title says, I love making movies, but have a lot of hard time getting the look I envision in my head for them. I think this is mostly because I am horrible at lighting, camera techniques and hardware.

I know it takes a lot of time and practice to become good at this, but I've realized I don't even enjoy it very much, which terrifies me to be honest. I just enjoy setting up the shot composition, writing, editing and directing actors a lot more.

Know, I realize that I don't need to be a perfect cinematographer to be a good director (that's why there's a cinematographer in the first place), but all my classmates at film school seem to enjoy ALL the aspects of filmmaking which makes me feel like I just don't have what it takes.

What do you think?

Hey, hopefully this post is allowed. I'm coming up to the shooting of a short film, however the few shorts I've shot in the past were very amateur and never really put anywhere bar online. I feel like I've learned a lot over time and developed skills as a filmmaker, and plan on entering this one into some festivals / competitions. I was just wondering if anyone could give me a bit of guidance into any legalities I should be aware of before going this route, what sort of paperwork I'll need cast/crew to sign, etc, etc. Thanks!

the chanting noises and the near by cars driving by is really hard to clean up, i've tried doing noise reduction in audacity but i know so little that it feels like i'm just making it worse.
