How should I approach learning to draw, if my goal is to start sculpting. Getting good and technical skills with pen and pencil (or tablet) is not my prime interest, I'd just like to develop good fundamentals.
Should I go throught the sticky resources anyway?

Mind you, I'm in my 30s, I'd really rather not spend 5 years training something that would be of little value or have small carry-over to the technical sides of sculpting. Just any insight is very welcomed to me here.

I was reading up on some sources and it was mentioned that I should put emphasise on perspective, compositing and composition and avoid learning sight-see drawing and drawing technically intensive anatomy, since you should practice that with material and not pen and paper.
Does that advice hold any real value?
