Everyone is born creative; everyone is given a box of crayons in kindergarten. Then when you hit puberty they take the crayons away and replace them with dry, uninspiring books on algebra, history, etc. Being suddenly hit years later with the 'creative bug' is just a wee voice telling you, 'I'd like my crayons back, please.
Normally, in anything I do, I'm fairly miserable. I do it, and I get grumpy because there is a huge, vast gulf, this aching disparity, between the platonic ideal of the project that was living in my head, and the small, sad, wizened, shaking, squeaking thing that I actually produce.
