Existentialist Fiction discussion

existentialism is all about the reasoning that we all make our own heaven and hell by the choices we make and the actions we take. I found online what I think is a good explanation of the concept:

Existentialism is a philosophical way of thinking that is very different from other philosophical ideas. It was started by the Danish philosopher Søren Kierkegaard (1813–1855). It sees humans, with will and consciousness, as being on a world of objects which do not have those qualities. As it developed in the 20th century, it was an atheistic philosophy. Most of its main thinkers and writers were in Europe.
Many religions and philosophies (ways of thinking about the world) say that human life has a meaning (or a purpose). But people who believe in existentialism think that the world and human life have no meaning unless people give them meanings: "existence precedes (is before) essence".
Existentialists believe that our human essence or nature (way of being in the world) is entirely and simply existence (being in the world). This means that the only nature we as humans have is the nature we make for ourselves. As a result of this, existentialists think that the actions or choices that a person makes are very important. They believe that every person has to decide for themselves what is right and wrong, and what is good and bad.
People who believe in existentialism ask questions like "what is it like to be a human (a person) in the world?" and "how can we understand human freedom (what it means for a person to be free)?" Existentialism is very often connected with negative emotions, such as anxiety (worrying), dread (a very strong fear), and mortality (awareness of our own death).
Existentialism is different from Nihilism. Nihilists believe that human life does not have a meaning (or a purpose) at all.
