The righteous man strives for self-improvement knowing that he has daily need of repentance for his misdeeds or his neglect. He is not so much concerned about what he can get but more about how much he can give to others, knowing that along that course only can he find true happiness. He endeavors to make each day his masterpiece so that at night’s close he can witness in his soul and to his God that whatever has come to his hand that day, he has done to the best of his ability.
