Is he not free from the fear of failing that annoys the strivers ?

我看资料上翻译是：难道他摆脱了困扰奋发上进者恐惧吗？

He is alive with enthusiasm.

他热情奋发。

The real pizzazz is the brave under heavy pressure, the confidence under adversity, the stir in arduousness, and the adaptation and modulability in any environment.

真正潇洒，是在重压下勇，逆自信力，是在艰苦奋发，是在任何环所具备自适应，自调节能力。
