Honestly, the text I most like for just starting in differential geometry is the one by Wolfgang Kuhnel, called "Differential Geometry: curves - surfaces - manifolds." He starts with differential geometry of curves and surfaces (which most undergraduate courses will cover), and then goes into some smooth manifold theory, Riemannian geometry, etc. So I ask: does anybody have any information/ advice on reading the Sternberg text if anyone knows anything about it? Is it normal that I'm struggling as much as I am with Sternberg as much as I am? Is there a better starting placing for learning this subject than Sternberg's text? Later, I found that there's another text "Elementary Differential Geometry" by Pressley that most first courses in differential geometry cover, and I noticed 2/3rds of that book is completely contained in the first CHAPTER of Sternberg's text. I've studied analysis in the past, so I feel like I grasp the prerequisites it recommends, but it's still extremely difficult. That being said, upon starting the book, I got about 20 pages in and realized that this book, to me, is very, very hard and very dense, despite being used as an undergraduate text. I recently picked up a text called "Curvature in Mathematics and Physics" by Shlomo Sternberg with the goal of learning Relativity from as much of a mathematical viewpoint as possible.
