India, June 5 -- Microsoft co-founder Bill Gates is writing yet another book. This time, it is about his "relationships, lessons, and experiences that laid the foundation for everything in his life". The memoir, "Source Code," is set to be published in February next year. It will delve into his formative years-from childhood to leaving Harvard and co-founding Microsoft with Paul Allen.
