Confusion

What is man seeking from his life ? What makes one feel that his life is meaningful ? Do people who seem to be satisfied with their life, are so because they have accepted that this is life ? Do people's dream ever come true ? If yes, what motivates them to move on ? When does man realize the futility of his deeds ? Does any of this makes sense ? Does writing a blog makes sense ? Seek truth is the doctraine of most of the religions in the world. What difference does it make if you know truth ? Sometimes, I wonder whether the man not intelligent enough to question and understand is the blissful soul ? Is it a boon to be Forrest Gump. Maybe the path and the goal, both are insignificant. Maybe it will take me million rebirths for my soul to rest, if there are rebirths. Maybe it will end up in hell, if there is heaven and hell. But does it matter ?
If nothing matters then why should we worry ?
