The provided text is a "Publisher's Note" from a book titled Personality Development, which compiles the teachings of Swami Vivekananda. Here is the gist:

Developing one’s personality is described as both a challenging and rewarding endeavor, essential for success in any field. It is a particularly vital pursuit for the youth, requiring disciplined effort, perseverance, and methodical labor. The publisher emphasizes that no effort in this direction is ever wasted; rather, the rewards are always proportionate to the attempt made.

To assist in this journey, the book systematically culls constructive ideas from Vivekananda’s extensive lectures and writings. Originally compiled in 1999 by the Sri Ramakrishna Ashrama, Mysore, this reprint aims to provide the younger generation with a clear roadmap for self-improvement and character building.
