my head aches

I'm still thinking, I've been thinking since twenty years what life is and why I'm here in this world, at times it seems like I've found the answer, but then thousands of other answers come up and my mind starts buzzing and then I get exhausted and go to sleep........lol......sometimes I think I'm mad, because I think I've got such a stupid and simple and trite question in my mind, that I don't think like a normal man would, about normal life, like about things happening here and there, like my career, my girl friend, etc........Well, I do think about these ordinary things, but then as I lay on my bed, my mind is gradually set up for the same question. I've read many books, listened to wise people, watched great movies etc which attempt to provide an answer to the eternal question, why are we here, what's the goal of human life, and who brought us here.....The answers are always fascinating and thought provoking ones, but to find the most appropriate answer is seeming like a big task................
   
But I won't give up, I'm gonna have to find an answer to this monstrous question....
What would be your simple answer to this question??
