[This Week's Books] "Let Them Theory" and More

Let Them Theory

The author argues that the reason relationships can be difficult in daily life is because we hand over the power to lead our own lives to others. We spend excessive energy and time on things we cannot control, such as the expectations, words, and emotions of others. So how can each of us find the path to happiness we deserve? The author presents the technique of "Let Them" (leaving things be) as a solution. After explaining how to separate negative emotions from situations, the author introduces the skill of "doing it myself" to maintain the life and relationships we truly want.

The book describes experiences ranging from working at a small gallery in Brooklyn to becoming a security guard at the Guggenheim Museum, silently encountering various artworks. She sheds light on the duality of art, where "What is this?" and "This is truly beautiful" coexist, and shares her journey to find answers to the questions: "What is good art? What is beauty?"

Behavioral Economics of Real Estate

Among the many factors that influence the real estate market-such as interest rates, the economy, and government policies-what is the most important variable? The author points to "psychology." He argues that differences in investment returns under the same circumstances are rooted in psychology. By analyzing the behavioral patterns of investors who make decisions based on memory, experience, habit, and inertia, the author identifies psychological and cognitive errors. He introduces useful behavioral economics perspectives based on macro variables such as interest rates, inflation, and employment. To reduce failure and regret, the author advises that one must first understand the behavioral patterns that lead to repeated mistakes. (Written by Choi Hwangsoo | One & One Books)
