What three sentences should I think about Zeng Guofan when my life is at a low ebb?

First, when you are frustrated and humiliated, you must grit your teeth and be inspirational, and you will learn from it. Don't be discouraged when you are frustrated. Second, the more the spirit is used, the more bitter the wisdom is. Our brains will inevitably become more and more flexible, so we should pay attention to practice and thinking at ordinary times. Third, there is only one way to deal with people in trouble. After doing your best, you must take it calmly. Everything depends on people, God disposes, and we will try our best to do everything well.
