Common Frustrations Amoung Young Writers

Inspiration can come at the most random moments. I find it aggravating how you can lay in bed or stare at your ceiling for hours and no ideas can come to mind. Boom! You're having lunch or at a museum when an amazing book prompt comes to mind. Or does anybody out there struggle with creativity sometimes? Occasionally I will be writing only to realize that I have copied an idea from another book series I just read. Another problem I struggle with is names. It is next to impossible to come up with something original that hasn't been used in twenty other books.
