The Book of The Underdog was first recommended to me by my girlfriend. She was worried that my career was stagnating (it was). Low and behold, I am now the star producer at my new company, where I moved through the ranks in little less than five months. Before that, I worked for 3 years in the same role, same pay. Zero advancement. Always afraid I was getting the boot.
According to its author, the key to advancement rests in understanding people's psychology. People don't just act randomly, there are specific triggers and pullers. People in power play by the rules described in this book. I feel I am wiser now. I am no longer beholden to my fears. I stick to my guts. I act with proper mood. I voice my opinions and own them. I am empowered.
