What is the three-character song of pupils' mental health?

The trilogy of mental health of primary school students is as follows:

1, life. The road of life is tortuous. People are easy to get old and have unlimited fame, and making a living will be challenged.

2. Make up your mind. People's spring begins when they are young and thinking about the future. If you have a successful career, you are determined to win. If you stick into a needle, you can wear a stone.

3. Self-knowledge. It is easy to know people, difficult to know yourself, and difficult to live in the world. Know the wisdom of others, give birth to discerning people, know yourself and know yourself, and fight every battle.

Step 4 be reasonable. Integrity, justice, understanding of morality and friendliness. All virtues come first, love comes first, love people and love nature.

5. Self-love. Love yourself, don't be greedy, foster strengths and avoid weaknesses. Accept me, like myself, be modest, be modest.
