Answer:
I belong to you but others use me more often than you do
I soar without wings I see without eyes. I've traveled the universe to and fro. I've conquered the world yet I've never been anywhere but home.
What has one eye but cannot see?
You write on me and secrets I can keep in places never seen. I spin like a top. Though stiff as a board, I'm often described like a mop. What am I?
I am owned by the poor, the rich do not need me. If you eat me, you will die! What am I?
Nothing specific, but more than a few. This many clustered, together will do.
