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 whole but incomplete. I have no eyes, yet I see. You can see, and see right through me. My largest part is one fourth of what I once was.
I'm white, I'm round, but not always around. Sometimes you see me, sometimes you don't.
What I am filled, I can point the way. When I am empty. Nothing moves me. I have two skins. One without and one within.
The more of it there is, the less you see.
If itβs information you seek, come and see me. If itβs pairs of letters you need, I have consecutively three. What am I?
