Paul Lemberg, successful advisor and author should know and he says it's required reading…

"I've worked with hundreds of CEOs and I always tell them, if it isn't fun—if it's not rewarding and satisfying—don't do it. Now I'm going to make Bechtold's Will Work for Fun required reading, so they have the exact same road map to turn their passions into profits and, as Bechtold says, 'make their play pay.' Give this book to your children. It will help them get a head start on the only sane way to earn a living: doing what you love for money."
