"I have been trying to write for a while now. I have all these amazing ideas, but its really hard getting my thoughts onto paper. Thus, my ideas never really come to fruition. Do you have any advice?"
Neil Gaiman responded (in good humor):
Write the ideas down. If they are going to be stories, try and tell the stories you would like to read. Finish the things you start to write. Do it a lot and you will be a writer. The only way to do it is to do it.
