Flow is being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you're using your skills to the utmost.
热爱真理,但宽恕错误。
海洋养育了数百万人,确保它能为子孙后代继续这样做是我们的责任。
