Existentialism

Existentialism is a philosophical movement that posits that individuals create the meaning and essence of their lives, as opposed to deities or authorities creating it for them.

Existentialism tends to focus on the question of human existence — the feeling that there is no purpose, indeed nothing, at the core of existence. Finding a way to counter this nothingness, by embracing existence, is the fundamental theme of existentialism, and the root of the philosophy's name. Given that someone who believes in reality might be called a "realist", and someone who believes in a deity might be called a "theist", therefore someone who believes fundamentally only in existence, and seeks to find meaning in his or her life solely by embracing existence, is an existentialist.

Existentialism is an extreme theory but can be applied to success. Someone who believes they were put here for a reason and continually seeks meaning in their life could be an existentialist. These existentialists that continually look for their meaning may become successful when they find it.
