Nightmares are not only the things that keep you awake at night. They are the worry at the back of your mind, they little foxes that burn down your vineyard or even the last fearful thought that popped into your mind.
As an artist those nightmares are very common, but sometimes they make me obstinate! My neck feels stiffer with anger at those nightmares, they make me paint over a crap painting, they make me try again when I thought I had no more power left in me. So, after my nightmare has passed, I look back on my journey and see that I have become a better artist because of it.
