"I have a bad tendency to get rapidly bored with my own material, so rewriting is hard for me. I mean, I already know the story and would rather read something new"

This quote by Alan Dean Foster speaks with the problem of rewording one's own material. It suggests that Foster tends to become rapidly bored with his own work, making it difficult for him to return and modify it. This could be since he currently knows the story, and would rather check out something brand-new. This could be an indication of a lack of inspiration or enthusiasm for the material, or it could be a sign of perfectionism, where Foster is not pleased with the work he has actually currently done. Whatever the reason, it is clear that rewriting is an obstacle for Foster, and he would rather proceed to something brand-new.
