I don't know since when, our walking speed has become faster, our eating speed has become faster, our reading speed has become faster, our work speed has become faster, transportation has become faster, communication has become faster, and even love has become faster than before... But our happiness is getting less and less day by day. Unknowingly, we have become busy people who work silently in the reinforced concrete city all day long, and we have become confused people struggling in an impetuous society. In fact, many pressures in life are obstacles created by oneself; many pains in life are caused by oneself and oneself. When you let go of the ignorant comparisons and desires in your heart, slow down your body and mind, and savor life carefully, you will find that you are still the same person you were before, happy and not lacking in dreams. Only by slowing down can you have time to think; only by being quiet can you see your heart. In this way, you can see different aspects of life and feel the meaning and joy of life. I hope this book can slow down your running pace and give you a moment of rest. I hope that if you stop, you can read slowly, love slowly, sail your own boat slowly, grow slowly while moving forward, and move forward slowly while growing up.
