If human activities are not inspired by ideals, they will become empty and insignificant.

1. Ideal is a famous lamp in the darkness, which can illuminate every corner of the trekker's heart.

2. If a person does not determine the goal of sailing, any wind direction will not be favorable to him.

3. Ideals are like stars—we can never touch them, but like navigators, we can sail by the position of the stars.

4. Ideals cannot be conquered by reality, and the sparks of hope shine in the dark sky.

5. An ideal is a force!

6. People who have no ideals in life are pitiful people.

7. If we do not have ideals, our minds will fall into coma; if we do not engage in labor, how will our ideals be realized?
