Do you have a need so strong that if you don't do it your life doesn't feel like it is worth living. I find if I have a gap from creating and making art work I don't seem to fuction as well. I need to make things and create with my hands. I think it comes from a desire to visulize what thoughts I have inside so I can share them with others and to also express hidden desires and emotions in a constructive and safe way.
It is a need to journey down an unexplored path and to not know what is around the bend. To create the ending and to have others find meaning and pleasure from your work.
