I offer you a literary bargain in the field of the book dedicated to psychology, which is a fashionable theme for the high rate of psychological problems of the current society, due to the stress generated by the same situation in which you are currently living. Among other things, the speed at which work is worked and lived in general.
They are books with a lot of content and many pages, they are not pamphlets or anything that looks like it. These books will help you a lot in your life and you won't find them in any bookstore today. They contain techniques and ideas that will help you find inner peace.
They are not entirely new, but almost because their state is of excellent condition and sharpness. Almost new.
