As the saying goes, "Give a man a fish, feed him for a day. Teach a man how to fish, feed him for life." I've always had a problem with selecting appropriate books. It could be a problem that I'm a perfectionist, but it's starting to take over my life. I recently made a huge list of linear algebra books which I found in various "book-recommendation" type threads on different website (e.g. reddit, stackexchange, etc), and then proceeded by elimination to cross out books that were obviously too advanced for me or just plain rubbish. I'm fed up of this; every time I need to learn a new topic, the same thing happens, and it kills my initial enthusiasm. What I'm trying to find is a quicker and more efficient way of choosing math books. If you could also post your experience with this problem (or non-problem, depending on your personality), it would really help.
