Attitude determines everything. In a civilized school, a person's self-cultivation is very important, and mentality is the key to a person's success. Every successful person in life is the master of mentality. If a person has the mentality of learning only when he wants to learn and doing only when he wants to do it, then he will never achieve anything in his life. Just like the ancients said, "If you don't sweep one house, how can you sweep the world." Heaven does not create useless people. No matter how small everyone is, they have their own weight in their own eyes. Just like Haotian said: "I don't care where I am." What is in other people's hearts, but how I am in my own heart; in learning, we should be rich by ourselves, not by trusting others. "We can't change others, but we can change ourselves, but we can't change our learning." Situation can change the attitude towards learning; if we cannot get to the heights we hope for, it is best not to let depression permeate our hearts and lives. There is no success or failure in learning, only spiritual frustration. Wouldn't it be better if the pressure of spiritual frustration was not transformed into a motivation to move forward.
