There is no conclusion in human life. Death cannot pretend to be a conclusion, since it is somehow beyond the life.
We always have something to prove about our life, but when we think we can draw a conclusion, the life which goes on without any halt brings us in the middle of another process of proving something else.
To prove something means in fact to be able to repeat something from the process of preparing a conclusion during the various moments or stages of life.
Commonly, it is about a simple message with a few personal features and it is built from our childhood. It expresses the way by which we primarily meant to live, for instance, by being in the nearby of other persons, by avoiding the outer dangers, by fighting with our weakness, or by enjoying what we feel as being pleasant. The life enriches such simple messages, but it cannot modify them. They ever remain intentions which cannot reach to a conclusion.
The personal features are primarily derived from the constitution of our body. For instance, if we have the primary inclination for living a social life, it becomes a boastful, a humble, or a hostile social activity according to our physical beauty or ugliness.
Through repetition, the initial messages take different forms of hiding themselves from the raw state which they had in our childhood. When the messages become clearer to us, we are able to build a mask for them. The most skilful masks are wrongly taken as victories and conclusions. It is always difficult to repeat your primary message and to return to it when the ongoing life uncovers you. And it often does so in virtue of its indifference to the meanings we establish for it.
