People are very inspiring!
I find I draw a lot of inspiration from people. Although I don't like to be around too many people for too long (crowds drain my energy) I enjoy meeting different sorts of people. Anything from physical appearance to mannerisms, what people say and how they say things - these are all inspirational to me as a writer.
I don't use everything I see or hear but certain things that stand out from the "norm" I nearly always use. What intrigues me is how someone can say one short sentence, and even though I won't necessarily use that sentence in a story, the words spark off a whole scene for a book.
It doesn't take much to be inspired. You just have to be open to inspiration and be aware that it's lurking in the not-so-obvious places...
