Hillel the Younger

"Do not judge your fellow man until you have come into his situation."

"Do not separate yourself from the community."

"Do not say, "when I have leisure I will study," for you may never have leisure."

"A boor cannot be sin-fearing, an ignoramus cannot be pious, a bashful one cannot learn, a short-tempered person cannot teach, nor does anyone who does much business grow wise."

"במקום שאין אנשים, השתדל להיות איש."
