Thinking, Fast and Slow by Daniel Kahneman is a fascinating exploration of the human mind and its decision-making processes. Kahneman, a Nobel laureate in economics, delves into the two systems that drive our thinking - the fast, intuitive system and the slow, deliberate system. He discusses the biases and heuristics that often lead to irrational decisions and offers insights on how to make better choices. This book is not only relevant to finance but also applicable to various aspects of life.
