Some thought Goodall's findings were the result of extraordinary good luck. Those who knew her understood that "luck" had nothing to do with Jane's success. It was, rather, the result of persistent hard work. In an interview, Jane explained why she believed she had succeed in studying and understanding chimpanzees when others had failed: "I've always felt you don't have to be completely detached, emotionally uninvolved, to make precise observations. There's nothing wrong with feeling great empathy for your subjects." Jane's empathy for the chimps deepened during the rainy season when she caught glimpses of them huddled together beneath trees, cold, wet, and miserable. She noticed that baby chimps fared much better in bad weather because the mothers protected them from the elements. Goodall felt guilty going back to camp, where hot food and a warm bed awaited her.
