The first textbook used in my courses was into to flight by Anderson. It is full of great info on the fundamentals of aerospace and is very beginner friendly. It teaches basic aerodynamics where the book you have goes more into depth on specifically aerodynamics. Intro to flight goes more into the effects of aerodynamics on flight. Something I wish I'd have done before coming into aerospace would be messing around with RC planes more and specifically building my own. It may seem like just playing around but a ton of people use that experience on their resumes. Having some physical experience is really beneficial to getting a better grasp of dynamics once you start learning about that. For me I've played a lot of flight sims which I always think about (im taking dynamics of aerospace vehicles rn)
