I'm going to return to college starting Fall, 2019 as a physics major. In preparation, I've been going though various textbooks, studying the material and working the problems. The concepts I understand reasonably well. The problem? I'm horrible at drawing. I see some problems, especially in classical mechanics, where drawing a sketch of the problem is needed. I'm worried I'm going to miss out on an important detail or concept simply because I can't draw well enough. I know I don't have to draw a Mona Lisa or anything but I have trouble drawing three dimensional figures and I worry that'll be a problem when I'm trying to visualize something in spherical coordinates. Has anyone else had this issue?
