It's not because things are difficult that we dare not venture. It's because we dare not venture that they are difficult.

It's not because things are difficult that we dare not venture. It's because we dare not venture that they are difficult.

不是因为事情很难，我们才不敢冒险。因为我们不敢冒险，所以他们很困难。

-- Marcus Annaeus Seneca 马库斯·安纳尤斯·塞内卡
