Reason makes people rigorous in action and thoughtful. Reason makes people do things calmly, without arrogance or rashness. Reason makes people calm and gentle ... If emotional expression makes people feel rich emotions and discover the beauty of life, then reason can make people strategize and move towards a successful life path. For the human nature of "joys and sorrows, sickness and death", emotional people will have mixed feelings, while rational people will accept it calmly, adjust their mentality and continue to struggle for their careers and studies. On the road to success, we are not easy to be too sentimental and move forward wholeheartedly. We can't let emotions control our actions. Tagore said, "If you regret losing the sun, you will also miss the stars." Often reason can keep us from getting lost in the stormy waves. As for the well-known story of "mending after a sheep is dead", when the cage is broken and the sheep is lost, sensibility often makes people feel sad, sorry and annoyed, while rationality makes people forget the past, look forward and immediately take Cui Shi to mend the hole. This reflects efficiency and ability. Life is short, and we don't have much time to reminisce about the past. Rationality makes us cherish time more, improve work efficiency, be diligent in thinking, and face all kinds of difficulties in order to have the most correct solution. Rational people can slowly move towards success, but losing rationality can only lead to failure. Therefore, under no circumstances should we lose our minds. We must think rationally. Only rationality can lead people to success at the fastest speed, and rational life will be wonderful.
