According to existentialism, each man and each woman creates the essence (meaning) of their life; life is not determined by a supernatural god or an earthly authority, one is free. As such, one's ethical prime directives are action, freedom, and decision, thus, existentialism opposes rationalism and positivism. In seeking meaning to life, the existentialist looks to where people find meaning in life, in course of which using only reason as a source of meaning is insufficient; this gives rise to the emotions of anxiety and dread, felt in considering one's free will, and the concomitant awareness of death. According to Jean-Paul Sartre, existence precedes essence; the (essence) of one's life arises only after one comes to existence.
Søren Kierkegaard spoke about a "leap", arguing that life is full of absurdity, and one must make his and her own values in an indifferent world. One can live meaningfully (free of despair and anxiety) in an unconditional commitment to something finite, and devotes that meaningful life to the commitment, despite the vulnerability inherent to doing so.
Arthur Schopenhauer answered: "What is the meaning of life?" by stating that one's life reflects one's will, and that the will (life) is an aimless, irrational, and painful drive. Salvation, deliverance, and escape from suffering are in aesthetic contemplation, sympathy for others, and asceticism.
For Friedrich Nietzsche, life is worth living only if there are goals inspiring one to live. Accordingly, he saw nihilism ("all that happens is meaningless") as without goals. He stated that asceticism denies one's living in the world; stated that values are not objective facts, that are rationally necessary, universally binding commitments: our evaluations are interpretations, and not reflections of the world, as it is, in itself, and, therefore, all ideations take place from a particular perspective.
The galaxy, fate, etc., etc., makes what happens to you. As cheesy as this sounds, life is what you make out of it. When life gives you a task or event, it depends on what you do with it. Do it a certain way and you could become a professer of biology. Do it another and you might be an artist. Every decision counts. And, when you die, it depends on what you make out of what you did. You cannot make your own life events, but the way you react is a different story.
