Is a life without meaning, a life of pessimism?

The idea of meaninglessness and absurdity of life was widely explored by many scholars, one being Albert Camus.
In accordance with his philosophical theory of absurdism the universe’s irrationality and randomness indicates that it does not posses a specific purpose. Therefore, one should abandon the search for meaning and embrace the absurdity of life. According to Camus, the lack of meaning in our existence is not negative, simply neutral. Without innate meaning, one is free to do with their life as they wish so the notion of a meaningless life isn’t objectively a useless life, nor is it a negative one.
