Don't treat knowledge as experience, only experience can cure your OCD

Knowledge versus experience
A book is consist of words, when you read it, your brain reconstruct the things that book's author want you understand. In other words, book's author pass his thinking through sentences and words. Knowledge is like a book in your brain, you can remember and understand it. A book can be seen as  a copy of other's thinking and partial experience. But you can construct my taste of an food through my writing for that food. The answer is no, you cannot, even I wrote  ten million words to describe the taste I experienced.
