一位哲人说过:“开始是我们创造习惯,后来是习惯制造我们。”有人做过一个实验:将青蛙放在冷水中慢慢加温,到它感受到温度高而想跳离的时候已经晚了;但将青蛙放入热水中,它立即跳起逃开了。这说明:当环境缓慢发生变化时,人就会产生一种与生俱来的惰性,形成了某种相对固定的习惯 A philosopher once said: “We started to create habits, and then we used to make us.” Someone did an experiment: put the frog in cold water and warm it, until it feels high temperature and you want to jump away. It was late; but put the frog into the hot water and it immediately jumped away and fled. This shows that when the environment changes slowly, people will have a natural inertia and form a relatively fixed habit.
