Send a diary. It says that a gentleman will always strive for self-improvement. The capacity of the earth is limited, so a gentleman must constantly cultivate his own virtue to undertake the world. The first sentence encourages him not to back down when he encounters setbacks. The second sentence advises him to be a man and start a business. Only by learning how to be a man can he succeed. In addition, let him record what happened in his business every day, how to solve it, and reflect on what he did badly that day and what needs improvement. This is entirely his own mirror. You can name this diary Wang Jitai.
