吾生也有涯，而知也无涯。从字面来说，这句话好像有两个意思，一个是顺其自然，既然知识无涯也不必刻意追求了。一个是正因为知识是无涯的，所以我们更应该好好珍惜时间，去追求真正重要的知识。那到底是什么知识呢？

Knowledge is a familiarity, awareness or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning.

Knowledge can refer to a theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); it can be more or less formal or systematic.[1] In philosophy, the study of knowledge is called epistemology; the philosopher Plato famously defined knowledge as "justified true belief", though this definition is now agreed by most analytic philosophers to be problematic because of the Gettier problems. However, several definitions of knowledge and theories to explain it exist.

问题的关键可是你要知道什么是最应该学习的，而且最高效的学习方法是什么？这个还需要慢慢探索。

最后，希望明天就能找到好哥们的妹妹！！！
