You know, I felt like I was missing something in my life too. I never even found it..it found me. I was really feeling this writing. Very good.

"Because it is invisible to the eye
My heart must search for it blinded"

Those lines I really liked. What you're looking for isn't something like money, girls, cars, or anything like that. That's what those lines made me think of.

"And if by chance it is found
Will i know my mission is acheived"

I liked those lines too. When what I was looking for found me, it hit me like a ton of bricks. I dunno what that has to do anything though..

"Just as no one knows
What lies beyond the shore
I will never find the answer
To what it is i search for."

Hopefully you'll realize what you're looking for. Good job here.
