It's the only thing that helps, tbh. If you can't see the world in like 4 shapes, you'll never be able to draw. You got the sphere, cone, cylinder, cube, etc.
Master those basics shapes before moving onto anything. When you're walking around IRL, look at things and think about their shapes.

now that I think about it, back when I was a teenager trying to learn how to draw, I did spend alot of time trying to draw shapes in different perspectives.
