I agree,that literature is too personal. So, when you are reading & the time is flying away with a speed of ..you know ..very quickly..; this book is very good, but only for you. And on the contrary, you are trying to read something with hard efforts, you are working very hard, try to begin again &again, only coz somebody says :"Oh, its
perfect, very usefull, or, simple, very modern". In last , this literature is bad, but the
same, ONLY for you!
