This is personality development book written by Shiv khera. I read this book during high school days. It was a well written book sold over a million copy. This was my first and last book i read in personality development genre. What i really felt accumulating superior knowledge in your concerned interest will increase your motivation and confidence. The personality development book will boost confidence just for a short time. The ultimate personality development comes from personal motivation and superior knowledge. So this is my first and last review of personality development book. Instead of reading books on personality development , I can spend quality time on reading some books on career and interest.
