I just wish I read this book at 20 unstead of 50. It would have saved me years and years of stress, misery, debt and working at jobs I hated, trapped by overspending. This book makes you realise that EVERYTHING you buy is paid for with your life energy, and all those little 'treats' you buy yourself (which only give fleeting pleasure, then it's on to the next one) to compensate for being unhappy at your job actually dig you deeper into the hole, and perpetuate the cycle. This book explains the wonderful concept of knowing when you have 'enough'. Too little is stressful, too much is stressful. Enough is what makes you happiest, when you truly love and enjoy everything you own. This book should be read by every young person starting on their working life, so that they don't make the same mistakes that many of us have made.
