However, labor is an unparalleled source of all strength, all morality and all happiness.

Career is a railing, and we hold it on the edge of the abyss.

Happiness exists in life, while life exists in labor.

Happiness will only be given to those who are not afraid of labor, and to those who have worked selflessly for many years.

You can find your own happiness in study, labor, science and selfless service to the people.
