For the sake of Perfection, strive to acquire the feeling of gratitude. But you cannot be grateful to the unseen G-d if you are not grateful to visible men.
We must overcome the arrogant attitude that all pleasure and happiness are owing to us, and that all men must serve us. A selfish man cannot be a true servant of G-d. We must understand that nothing is free, and that we must pay for every benefit received. — Rejoice, O Youth
