I feel that procrastination is my brain's way of saying it needs a pause. I read, research things, watch mindless movies, or draw doodles while listening to music and then a day or two later, BAM! Inspiration is back and I can write again.
I used to feel very guilty about it until I read this quote by Tove Jansson:
"Duty and pleasure are a long story for me, permanently relevant, and I've gradually reached an unusual and altogether personal conclusion. The only honest thing is pleasure - desire, joy - and nothing I've forced myself to do has ever given pleasure to the people round me"
I quit feeling guilty ever since and I've never been as productive as now!
