Showing one's best is essentially different from showing off. It is a quality not everybody can be good at.
的人表现出最好的一面，这与炫耀本质上是不同的。这是一种品质，不是每个人都能做到的。
In order to show your best, you are advised to do three things. First, you should equip yourself with the knowledge you can acquire. Only thus can you be confident of yourself. Second in importance is a good command of verbal skills. This is how effectively you will be able to make yourself convincing. My last advice is modesty. Don't let others suspect you are being arrogant and showing off.
为了显示你的最佳状态，建议你做三件事。首先，你应该用你能获得的知识装备自己。只有这样你才能对自己有信心。第二重要的是良好的语言能力。这就是你如何有效地让自己变得有说服力。我最后的建议是谦虚。不要让别人怀疑你傲慢和炫耀。
