Titles

The other day I got into a conversation with a good friend over the importance of titling art work. I realized in this conversation that I have yet to title any of my work though I have created hundreds of pieces. So now I have many questions to pose. Such as, does art need a title? Has all the work I have created actually been art if I can not conceive a title for it? How important is having a title for a piece? How can you approach a piece if it has no name? These are all questions I don't necessarily have the answers for, but am most certainly not looking for answers. I suppose the reason why I have never put farther thought into my work (other than naming it based off of subject matter) is because my work is created from emotions rather than words so putting a piece into words that was created from something beyond words seems improper. But now, after this conversation I am left with this need to "title" my work, but I have no idea where to start. I suppose through time, and thought I will learn, but right now it's something that eludes me.
