Why/ how do you write so many fanfics?

I write them because I love them and I love getting comments on what people do and don't like about my writing. It helps me to become a better author. 

How, you ask, @Cinder1221? I honestly don't have any idea.

I come up with the ideas at the most random of times; in the shower, duiring choir, during gym, while doing my chores, you name it, the list is endless! Some of them end up being stupid and getting me nowhere..kinda like StLR. The idea was brilliant at first, but then it got harder and harder to come up with ideas for it. And now I have thousands of reads on a story that ran into a ten foot thick cement  wall. On the other hand, I have tGC which are going much better than i anticipated. The ideas keep coming and I pretty much know exactly how I want all the books to go.

It really just all depends. When it comes to my writing it's a complete hit or miss.

I hope that answered your question :)
