One day in the year 2007, I was in a library, reading a book by David Schwartz. Somewhere in the middle of this book, I felt like I had learned so much a half an hour reading the book than I could ever learn in one-year schooling.

If you're a reader, I bet this has happened to you a few times in the past. You pick up a book, download it for free on the internet, read it for free in the library or borrow it from a friend without paying a penny yet; such book ends up being more valuable to your success in life than a year of schooling or even the whole years you spent in the university.
