Michael McDonald is a famous singer who was part of the bands Steely Dan and The Doobie Brothers. He has also made music on his own. Even though he has many awards, he did not always feel like he had an important story to tell. But now, with the help of his friend, actor and comedian Paul Reiser, he has written a book about his life called "What a Fool Believes." In the book, Michael talks about his life from when he was young in Missouri to how he became a well-known musician. He tells about the good times and the hard times, like his fight against drinking too much alcohol and not always feeling sure of himself. He shares happy memories, like singing in famous albums and funny moments while playing music for others. Michael's book tells us that life can be unexpected and that it's important to go with the flow. He also gives advice to other musicians and shares funny stories from his career. Even when people made jokes about him, he kept going and later made some albums with music from Motown that people liked a lot. By writing his book, Michael has had a chance to think about his past and to stop feeling angry with people he thought got in his way. Now, at 72 years old, he is happy to share his life story with everyone.
