To exist is to think; but not to doubt.

The inevitable thought of wondering about the force that destiny takes into our lives is somehow a way for us, rational yet empty-purposed beings, to regain confidence in what lies ahead as the future and our skill to handle its obstacles in an appropiate manner in spite of lacking preparation in doing so. Trying to find the true nature of destiny, or debating the reliability of its existance along an entity that writes it, is never going to solve the individual's questions to aim for the truth, because there is not an explanation for purpose or meaning outside one self. The task of the rational person is to set him/herself into a journey towards self-knowledge; so that various options for values, motifs, skills and tastes can be explored and later taken freely, and an aristotelic eudaimonia can be reached by every individual. Taking a Camus-like posture, it's not about wondering if free-will exists, it's about realizing that you are rational and learning to master and take over your decisions and ideas to build yourself the destiny you want to have, no matter what the external circumstances wind up being. That way, the purpose of life will be so clear that no exhortation for destiny will ever be needed, because the path is being taken over by its individual and inspiration to follow it will come along with it.
