Author of quotes: Hillel

Thou shalt not be naked among the clothed, and clothed among the naked; do not appear standing among those who sit, and sitting among those who stand; do not be laughing among those who weep and weeping among those who laugh.

Whoever tries to glorify his name loses his name; who does not acquire new knowledge, loses the former.

Do not be lazy to study, do not say that you will learn later - after all, the ignoramus is not afraid of sin, and the Torah adds life and understanding. Work hard, and the wages that await you in this and the world to come will be according to your work. Always remember whose reflection you are, and therefore, where there are no people, try to be a person.

If I am not for myself, who is for me? If I am (only) for myself, what am I? If not now, when?

Who, if not me, and when, if not now?

Not separated from society, for we are all one, do not judge your neighbor until you're in his place.

What is hateful to you, do not do to others - this is the whole Torah. The rest is commentary. Go and learn.
