Joel Salomon has done it again. The hedge fund manager turned financial coach has just released his second book. It gives you a step by step plan for building and maintaining wealth. Joel is big proponent of focusing your investing on several concepts and watching them like a hawk. That way if the gains are huge you'll be sure to reap the rewards. Diversification for diversification's sake is not a roadmap to prosperity, it's a way to achieve mediocre returns.
