"Doing Good Better" by William MacAskill is a thought-provoking book that introduces the concept of effective altruism—a philosophy and social movement that uses evidence and reason to determine the most effective ways to improve the world. Instead of simply doing good, MacAskill argues we should focus on doing the most good we can with our time, money, and resources. Through real-world examples and practical advice, he shows how small changes in our actions can have a disproportionately positive impact on the world.
