Answer:
By Moon or by Sun, I shall be found. Yet, if there's no light around, I am undone. What am I?
I belong to everyone. Sometimes make you happy sometimes make you sad. I will never end until the day you do.
I have memories but none of my own whatever's on my inside is what is shown. If I'm ever different it's because you changed me I feel like a decoration here for you to arrange me.
A hole in a pole. Though I fill a hole in white I'm used more by the day and less by the night
I have been the beginning of ideas for all time yet I am just one simple small object the things that you can use me for can be frustrating and also I can be pretty. I have some of the most valuable thing in the world on me yet almost everyone owns me.
Almost everyone needs it, asks for it, gives it. But almost nobody takes it.
