The contents are all written in Korean. This is something that came with the book when I bought it. It's structured as a question for each day, and you answer those questions. There are also famous quotes interspersed throughout. Daily Reflections: To have time to reflect on daily life through philosophical quotes and messages. Mindfulness: To aim for stress reduction and mental stability for modern people by utilizing historical philosophical thinking such as Stoicism. Self-Growth: To deepen one's own values and outlook on life through philosophical dialogue and consideration. How to Use: Provided through apps, journals (notebooks), social media, etc., to help make it a habit. It functions as a self-care tool to incorporate "thinking" time into daily life and live a richer, more peaceful life. ♻️It will be shipped compactly after being packed using recycled materials.
