Maybe the hope in a future solution to actual problems of life is similar to the acceptance of a total failure in dealing with them.
Because both the still non-existent future and the naught of the failure make someone to live with a certain amount of total misunderstanding about his life.
When the hopes prove to be unfounded, it is not primarily caused the disappointment of recognizing a failure, but rather the man is confronted with the difficulty of having his life as a matter of understanding.
For this reason, hopes are kept even if nothing gives credentials for the fact that they can be ever fulfilled. By not recognizing their impossibility, the lack of understanding is doubled.
Still, it is greater the damage of wasting yourself in understanding the life, since it cannot be fully understood.
