《淮南子·缪称训》
君子不以为小的善事不值得做而就舍弃它，因为小善积累起来也就能成为大善；也不以为小的坏事做做也无妨而去做，因为小恶积累起来也就成为大恶。
君子不谓小善不足为也而舍之，小善积而为大善；不谓小不善为无伤也而为之，小不善积而为大不善。
A gentleman will never abandon a good deed for being too small, because small acts of good can accumulate into great good; he will never do a small evil deed, because small acts of evil can accumulate into great evil.
