Anyone seen my motivation??

I'm getting near to the end of these paintings, I finished no 5 yesterday which I need to get a photo of and started the last one today but I seem to have mislaid my motivation! I sometimes find starting a painting difficult because, before it starts to take form, I just can't visualise what I'm meant to be doing so this morning has been spent sitting, staring at the painting, adding a bit of paint, coming down to check my emails, then repeat. I've got this afternoon and 2 whole days left in which to finish this painting and varnish it as it's hanging day on Saturday. Please, if you see my motivation wandering past you, return it to me as soon as possible, I miss it very much!
