一：篇章

㊀ His tireless workers

1:Brown

If Musk worked a twenty-hour day, so too did Brown.

得力助手Brown，生活中工作上都是Elon的 loyal assistant，还关注工作环境中细节，细微至留意垃圾桶清洁；工作中涉及与Elon相关事宜认真严肃，而与同事日常交往中热情随和，也是Elon的情绪“晴雨表”。推动SpaceX初期发展的一位功臣。

2:All-star crew：

有经验丰富知识渊博的开国老臣，也有年轻名校毕业、Elon亲选的得力干将。面对Elon制定知道火箭的Timeline的紧迫时间，他们更多是行动。

Chris Thompson, a onetime marine who had managed the production of the Delta and Titan rockets at Boeing, joined as the vice president of operations. Tim Buzza also came from Boeing, where he'd earned a reputation as one of the world's leading rocket testers.Kevin Brogan was employee No. 23 and came from TRW

㊁The first stage of the rocket—the construction of a gas generator

两引擎的调试—Merlin and Kestrel came with challenges，整个过程：error and trial，有工程师们同心协力、屡败屡战，也有Elon的亲历亲为和正确的领导，虽极其期待成功但面对失败时对员工也是谅解的鼓励。测试引擎整个应该和居里夫人提取釉一般艰辛吧，最终Elon也让全世界看到他和这群拼命员工们的成果

What Musk would not tolerate were excuses or the lack of a clear plan of attack.

㊂ His daily life during this period

初当父亲而却意外丧子，内心的悲伤仅向几个亲密朋友透露，未在平时表达过多的伤心之感，因为自己认为谈论这些悲伤之事无益于身边的人和以后的生活，而自己不知道该如何合理对待。过于冷静会伤伤心的人，例如Elon妻子那时的心情。而过多悲伤却无益于将来。而最难的就是“适度”。

I'm not sure why I'd  want to talk about extremely sad events. It does no good for the future. If you've  got other kids and obligations, then wallowing in sadness does no good for anyone around you. I'm not sure what should be done in such situations
