Existentialism and Common senses

Doubtless, we are living in the age of existentialism. But a relevant significant point to existentialism is: "since existentialism is depend on individuals, there could not be a common rule for all individuals to do and follow and so every individual has to follow h/is own way of thought. So nothing to share with others and nothing to ask of others, because of difference in very fundamental part of human existence.
I believe that, we need to revalue it, in order to make it more depend on society, more depend on human community; and more depend on common rules. 

But no doubt, existentialism is prior to common senses.

Philosophical Suicide - a misunderstanding of Kierkegaard's Philosophy

Religious, spiritual, or abstract belief in a transcendent realm, being, or idea: a solution in which one believes in the existence of a reality that is beyond the Absurd, and, as such, has meaning. Kierkegaard stated that a belief in anything beyond the Absurd requires a non-rational but perhaps necessary religious acceptance in such an intangible and empirically unprovable thing (now commonly referred to as a "leap of faith"). However, Camus regarded this solution, and others, as "philosophical suicide".

Why is it so? This misunderstanding - philosophical suicide - occurs because of having no experience of belief's state, which is not reachable for everyone. There could be also a misconception of goal of philosophy in human's life.

Lord! Give us weak eyes for things of no account (not importance), and eyes of full clarity in all truth.
