I agree with you that learning from experience is far better than learning from book. When you read a book, the most you can get from it are visual, audible, and perception (which involve your brain). I'm talking about senses here. In contrast, when we experience something, more senses are involving in the experience( includes taste and touch), which help make learning faster and easier.
By the way, I will try to help you correct your grammar. This is the way I learn how to improve my writing by recognizing other people's mistake.
Learning is a specific subject for people. Some people learn better from experience, others learn better from book. In my opinion, the best way to learning(I think you can say: 'the best way to learn is... or 'the best way of learning is...)is getting experience. My arguments for this point are listed as follows.
First of all, information from books are often depended on authors' view. For instance, I went to the United States two years ago. Before I went I had read a travelling book. (You can combine two sentences above by: For instance, before I went to the United States two years ago, i had read a traveling book, which I did not remember the author's name.)I do not remember author's name.In the book, he expressed his opinions about Manhattan and I created imagination for Manhattan to authors view. But when I went there I saw that Manhattan was very different place and I did not belive that situation. (Of course when you read a book describing about someplace, you will imagine about that place according to what you read. So, above sentences can rewrite like this: In the book, he expressed his opinions about Manhattan and how it looked like. However, when I arrived at Manhattan at the first time, I felt disappointment because the place was not like what being described in the book.--> It is just my suggestions)
Second, we can forget information(information, like water, is uncountable noun, so always takes singular form) which we learn from books. Because books can not affect us as well as experiences(Fragmented sentence here, I will try to combine your sentences above: Second, because books cannot affect us as well as experience, we can quickly forget information we learn from books). We can remember theories but sometimes we may forget them. Also, we can not truly before go or see,(<-- In addition, sometimes we cannot truly understand these theories unless we can experiment them.)However, we can not know some historical informations but for instance, if we go that historical place, the informations come our mind easily and ew realized them (<--to clarify what you tried to say, here: Another example, we can learn historical information better if we can go to or see these historical places.
In conclusion, books give us just theroical informations, if we want to know or to get experience we should live them.
Good luck with your study and experience. By the way, I lived in Minnesota and have never been to New York. Should I learn about it from you or should I visit New York? I moved to the US three years ago. Learning how to write has been really challenging for me, but it is good to see your writing improving everyday. So, just keep doing it everyday. Good luck.
