#以太坊 Those who are restless and careless will achieve nothing, and those who are calm will be self-contained. A good attitude is a great wisdom. Nine times out of ten, life is unsatisfactory, since you can't change the encounter, you have to learn to change your mentality. Those who have light in their hearts are the true wise men. That light is soft enough to control one's emotions. Be a person with light in your heart, don't get angry when you encounter things, don't complain, know how to smile, and know how to move forward.
