“I [who study Torah all day] am God’s creature and my fellow [at his work] is His creature. My work is in the city. His work is in the field. I rise early to do my work and he, likewise, rises early to do his. Just as he is not able to boast of being able to do my work, so I cannot boast of being able to do his. And in case your disciples ever say, 'but I study much Torah while he studies little,' have we not learned that whether you study much or little, the reward is yours, providing you direct your heart to heaven.” - Berachot 17a
