I like the freedom to just create without the pressure of giving it a title. As people like to say, "It is what it is." Half the time, I don't know what I've drawn, so I don't want to limit people by telling them what it is.
I recognize that having things unnamed can be frustrating for some because of our need to categorize and put things into place, but it's important for me not to force myself to title my work if I don't want to.
