“How strange and foolish is man. He loses his health in gaining wealth. Then, to regain health he wastes his wealth. He ruins his present while worrying about his future, but weeps in the future by recalling his past. He lives as though death shall never come to him, but dies in a way as if he were never born.”

— Imam Ali (r.a.)
