As food is to the body, so is learning to the mind.Our bodies grow and muscles develop with the intake of adequate nutritious food.Likewise, we should keep learning day by day to maintain our keen mental power and expand our intellectual capacity.Constant learning supplies us with inexhaustible fuel for driving us to sharpen our power of reasoning, analysis, and judgment.Learning incessantly is the surest way to keep pace with the times in the information age, and an infallible warrant of success in times of uncertainty.

　　学习之于心灵，就像食物之于身体一样。摄取了适量的营养食物，我们的身体得以生长而肌肉得以发达。同样地，我们应该日复一日不断地学习以保持我们敏锐的心智能力，并扩充我们的智力容量。不断的学习提供我们用不尽的燃料，来驱使我们磨利我们的推理、分析和判断的能力。持续的学习是在信息时代中跟时代并驾齐驱的最稳当的方法，也是在变动的世代中成功的可靠保证。
