What is the next sentence of the proverb "A knife will rust if it is not sharpened"?

Knife will rust if it is not sharpened; People who don't learn will fall behind.

Just like a person, although he knows the importance of diligence for a person's growth. If you don't keep a clear head and keep pace with the times, you will not be able to master the latest science and technology, you will be slow to respond to the surrounding environment, you will not be able to adapt to the new changes in the environment, and you will eventually be whipped by society. Therefore, you can't relax yourself and keep strong learning motivation at all times.

Lev tolstoy said: "There must be goals in life, goals in life, goals in a period of time, goals in a year, goals in a month, goals in a week, goals in an hour and goals in a minute."

In short, you should have a goal in life. When we carry out our goals, we should not blindly stick to previous experience or acquired knowledge, but keep learning and practicing at any time according to the needs of the times or the environment, so as to keep pace with the times on the road to achieving our goals and get twice the result with half the effort.
