I recently started another painting, this time in a huge canvas and, even though I know exactly what I want to paint, I can't get myself to finish it.

I bought this canvas two weeks ago and in the same day painted the blue sky with clouds background. Now, somehow, every time I look at it and think of finishing it I get scared and I don't know why. Maybe it's the fear of not being able to paint it the way I envisioned it, or maybe it's just another stupid symptom of the inertia I've been feeling lately for all things that involve more that eating, sleeping or watching movies...
