Can I ever relate to this topic, right down to doing laundry or windows instead! Believe me, I'd rather be painting.
I have to say that with me it is usually there - this dreaded absence of courage. My hubby will question this, which I must say, doesn't help matters too much. Not being an artist himself but a realist by nature, he says "just pick up the brush and paint". Hum-m-m, well.
I will say that I feel better to hear all of this, as though seeing it in print from others in some way makes me feel more well, uh NORMAL. It can be a lonely sight sitting out there in front of an all white "painting to be".
But nevertherless, be brave my friends, be brave. It's only your life we are talking about.
