我们不仅要追求技术的领先，更要追求技术的实用性和普及性。
We should not only pursue technological leadership but also the practicality and popularity of technology.
The fact that people are full of greed, fear, or folly is predictable. The sequence is not predictable.
道理明白则文辞畅达，气势充沛则言辞得当。
Fear is just a feeling. Don’t let it stop you.
【原文】颜渊喟然叹曰：“仰之弥高，钻之弥坚；瞻之在前，忽焉在后。夫子循循然善诱人，博我以文，约我以礼，欲罢不能。既竭吾才，如有所立卓尔。虽欲从之，末由也已。”【译文】颜渊感叹地说：“(老师的道德和学问)抬头仰望，越仰望越觉得高耸，努力钻研，越钻研越觉得深厚；看着好象就在前面，忽然又像是在后面。老师步步引导，用知识丰富我，用礼法约束我，想停止前进都不能。我竭尽全力，仍然像有座高山矗立眼前，虽然我想攀上去，却没有途径。”
