Swami Purushottamananda, who had inspired several hundreds of youth, had written three booklets dealing with the need and practice of concentration, how to study systematically and face examinations with confidence, and how time is to be saved and used for career building. For the sake of convenience, the contents of all the three booklets have been brought out in this single volume. The readers, especially the youth and students, will find the ideas in this volume very helpful.
