How do you know all about movies if you have a real career?
Doesn't it take work? Most people have a family!
I'm a struggling musician, just started violin but can play a lot. I'm due to be in a college orchestra in the fall and spring, don't have to be a student and don't have to pay anything.
I know over 200 songs well enough to perform and get paid for, in some way, shape, or form.
