I recommend "Puppy Money". This book is about both financial management concepts and life attitudes. If a person wants to be happier, the most important thing is not to make more money, but to change himself first and live a more positive life. "Puppy Money" is an easy-to-understand financial fairy tale. The author Bodo Schaefer was born in Germany in 1960. He once experienced a serious personal financial crisis. Later, he extracted a set of investment concepts from his own experience and became a best-selling author. He is known as "Europe's No. 1 Money Coach" .
