Both teaches us almost similar things with the only difference that, whatever we learn from books are ideal things. On the other hand, experiences teaches us practical things.
brilliant idea !!
I like your explaining, I can catch what you meant.
In addition to effective memory, when we learn from experiences, along with the basics we also learn different modifications of the thing which we discover while practicing it. And this sometimes make things much easier and faster. For example, I had learnt from my textbooks about different instruments which are used in root canal treatment. But what if you are about do a patient and discovered that some of the instruments are not available or are damaged? The answer to this, I had learnt from my experience, that how any other instrument can be used to function in the same way as the required instrument.
Personally, in such paragraph I suggest you to add the beneficial of gaining knowledge from book instead of experience. It can make the comparison and contrast that the prompt required look more clearly.
