@oftenly,
I love this book, it's one of my favorite works of philosophy.
The issue with this quote of yours, and with Camus in general, is that absurdity is inescapable. As soon as you
really think about life, you will not be able to avoid how absurd it is.
So lest we have a complete meltdown and kill ourselves (because there is nothing to live for), absurdity should be
accepted and perhaps even embraced.
In other words, we get to create our own meaning, our own happiness, and even in the face of the absurdity we do not collapse -- we don't need to collapse -- because our meaning comes from within.
If you want a brief but amazing short story by Camus that illustrates this, pick up a copy of
Exile and the Kingdom and read
The Adulterous Woman. It's about a woman on some bleak bus trip with her husband, it's stifling, it's meaningless. And at night she can't take it any more and she runs outside and sort of "gives herself" to the stars in the sky -- and when she returns to the room with her husband she can't stop weeping. It's a gorgeously written story, and shows how in the face of absurdity there are moments of nihilism but also these lurid moments of sheer life.
Existentialism is a very psychologically-based philosophy. It's often better shown than explained.
