Struggling with self-learning economics through textbook readings

I am trying to self-learn introductory microeconomics by following a textbook, Microeconomics by Christopher T.S. Ragan. I am not currently enrolled in a course, I am just self-learning in preparation for a future introductory course in microeconomics. However, I find myself constantly getting stuck trying to understand explanations in the textbook and I am making minimal progress. To be honest, I have never learned a subject by simply reading a textbook (more of a class/videos person) and I am wondering if this strategy is inefficient.

Should I instead use the textbook as a reference material for practice problems and rely on videos/Khan academy to introduce myself to the concepts? Does relying on video/lectures make me a weaker student or disadvantage me once I take an intermediate economics class? I am not an economics major and I only require a handful of economics courses to complete my major. I am finding the process of self-learning to be really difficult and I would appreciate any advice/tips to be more efficient. Thank you.
