Am reading these two books when the similarity between them hit me like a bolt of lightning:     They are written by husband-and-wife teams. Which is amazing. I don’t think my wife and I could ever co-author a book because our interests and personalities are as different as day and night. Case in point: she loves planning and sticking to the plan. I love just wringing it. Opposites attract huh, like in the laws of magnetism. But what about you? Is there a common topic that you think you could co-write on with your wife, If you’re happily single, you could think of your best buddy and answer this question from that angle. Long Way Round was written by best buds Ewan McGregor and Charley Boorman.
