Answer:
I never was but always will be. No one ever saw me but everyone knows I exist. I give people the motivation to better themselves every day. What am I?
I am a mountain at night meadow at day
With a halo of water and a tongue of wood, stone as skin long I stood. What am I?
You find me behind the stars; or in a sixth seventh or third. It takes something round a computer and me to make pie. I am bigger than anything you can think of.
The more there is the less you see.
The more of me you take, the more I appear behind you. What am I?
