To add to this, people underestimate how long it might take understand material on a proper level. My favorite quote in Axler's linear algebra done right was that if you take less than an hour per page, your doing something wrong. I agree with him. Don't get me wrong, learning math is definitely worthwhile, but please don't think you can skim some books and gain profound insights without hard work.
