請解一解句英文既意思

hold= believe, regard; but = only
我認為這世界只是一個舞台,每人都必需要扮演一個角色，而我扮演的是一個憂傷的角色。

出處：The Merchant of Venice by William Shakespeare, directed by Michael Radford解說：Reminiscent of the philosopher Jaque's speech in As You Like It, "All the world's a stage,/And all the men and women merely players," this line is spoken by Antonio in an attempt to explain his recent melancholy to his friends (Gratiano).

原文應是：ANTONIO："I hold the world but as the world, Gratiano,
a stage where every man must play a part,
and mine a sad one." 我嘗試翻譯如下：安東尼奧：「我抱擁世界。然而…加烈提安奴…如世界是一個舞台，當中每人需參演一個角色的話，我就是一個悲哀的角色。」

我擁有這個世界，但是這個世界。
如一個舞臺，每個人必須扮演一個角色；
而我是一個悲哀的角色。

翻譯英文不是每字去翻譯. 是要全句或全文翻譯先可明白其意思

我舉行世界，但是作為世界。
一個階段，每個人必須扮演一個角色；
並且介意悲哀的。
