Existentialism

Existentialism is a modern philosophy which states that philosophical thinking depends on the individual's subjective belief or idea. One common form of Existentialism is when you state that philosophical questions and ideas like the meaning of our lives are rather individual-subjective than objective, no one created you for a reason, you created yourself for a reason that you may only find and define. Josef Fleming is considered to be the founder of Existentialism, thought he didn't use the term "existentialism".

Nihilism is usually confused with Existentialism and Absurdism, even thought there are differences. Existentialism says that you may apply a subjective meaning of life or simply live by subjective ideas, while Nihilism and Absurdism say that there are no objective or subjective ideas or meaning in life, applying a subjective meaning or having a subjective idea doesn't mean it's real.
