The simple fact that you have a desire to learn it is already good enough anon. It doesn't matter when or how you start, the difficulty is arbitrary and it's different for every person. I can confidently say that the one of the only reasons people make it out to be very difficult is because high school and university exams/tests exhaust students into specific types of questions, rather than the broader concept or fundamentals or proofs of the ideas that you will learn. So as long as you have this interest, just take it chapter by chapter with some good book, or some youtube video tutorials, do some examples, understand where all the things that you are using is coming from, and it will all tie very beautifully together. It's a wonderful subject that gets a lot more hate than it deserves
Good luck anon, believe in mathematics
