Farmers get 40 growing seasons in their lifetime, giving them just 40 chances to improve.
From the book's description on Amazon: "A son of legendary investor Warren Buffett (who provides the foreword), Howard G. Buffett considers himself a farmer first and foremost. He explains that all farmers get 40 growing seasons in their lifetime, giving them just 40 chances to improve. In 40 chapters—constructed as elegant essays—Buffett describes his quest to make a difference in the world, which began well before his father established philanthropic foundations for his three children. The younger Buffett has focused his foundation on wildlife conservation and world hunger. Here, he recounts his personal and professional experiences in surprisingly candid and colorful fashion. An accomplished photographer, Buffett humanizes his stories with his own pictures: from a young boy in ankle chains whom he encountered in Senegal, to a shy village girl in Sierra Madre, to a subsistence farmer digging zai pits in Mozambique. Buffett invites his son Howard W. Buffett, also a philanthropist, to contribute a few chapters, but unfortunately these miss the mark. Despite this shortcoming, the book successfully blends personal stories with a tough look at the struggle to fight domestic food scarcity and world hunger."
