Who likes to be a passer-by who wanders forever? If one day I hold my own soil in my hand and see the green grass growing slowly in the breeze under the clear sky, I will think of the harvest of one year and my down-to-earth mood, which is a good answer for the rest of my life. Almost every day life is faced with trade-offs. If you want to do everything, you will find that you can't do anything well. People's energy is limited, and we can't do everything well. What should we do? List our priorities, find the main theme of life, and once we hit the main theme, we must learn to give up.
