the blank canvas syndrome

so no picture right now... just words.
i seem to have a pinball machine in my head.... just little snippets of images that are potential subjects for my next painting.
The canvas has been purchased and the framework of ideas are all present, yet there is the unmotivated or perhaps timid hands.

somehow saying that you are nervous or anxious about something makes it seem less daunting. yes???

How come making a start is always the hardest part???
