I'd say go for it too
I was told when I was 19 by my driving instructor that there was no way on Earth I would ever get my license, but he was wrong. I got my license at age 20 (a few months later) and passed my road test on my first attempt. With driving, practice makes perfect. For me, I was able to convince my mom by telling her that with a license and a car, she wouldn't have to drive me to doctor's appointments, college classes, or work. Good luck!
