原来如此。那就说说其中的一个观点吧。

The best career is something that captures your passion (something you really like to do), your strength (something you are really good at), and something that makes money.

Sth you really like to do -- to understand yourself is not easy, very often we don't know what we really want;

Sth you are really good at -- this will reduce your opportunity cost (note: this is more of a self-examination, rather than comparing to others);

Sth that makes money -- a good technology/skill without a good market doesn't really help.

其他的就不多说了，仁者见仁，智者见智。
