I like to read books.

I agree more with the phrase “never judge a book by its cover”, because I do not think that people appearance often reflect who they really are. In fact, I think is a factor of misinterpretation of the people in a society with so much variety in the people nowadays.

The phrase "what you see is what you get" causes a particular problem, the discrimination of the people who do not enter in the spectrum of what is consider good or nice. When other people look bad to us, is nothing more than ours appreciation, and we should not judge them for it.

The inside of the people is more important than the appearance, and thinking that the exterior reflect the interior of the person only affects our vision of him, and prevent us to know that person better, losing a chance to know a friend in any other circumstance.

When we know a person in profundity, we get to understand them, and then we can judge them and get a real appreciation of them, doing this before know them, is not judge them, is just a prejudice, and that only serves to make mistake about the people who is around us.

In conclusion, No, we should never judge a book by its cover, the book can be actually really good if we give it an opportunity and read it, the cover is not a real reason to read it or not. The same thing goes with people. 

This is a series of books that the cover do not seem so good, but are the best books in history.
