I have long said "I'm totally right-brained", and blamed my lack of discipline on being so. It's a convenient excuse.
Artists are probably more right-brained in their (our) make up. I don't consider myself emotionally frail, but I have all my life been told how "different", "unique", etc., I am -- and believe me, it's not a compliment in many instances!
I have always marched to the beat of my own, singular, drummer. I feel things more than anyone I know; I am an extreme empathetic. It follows, therefore, that I see things differently, because I feel them.
I have long kept a pad of paper on my nightstand, because I will awaken with a vision or a phrase (most often) running through a dream, or my conscious or semiconscious brain. It might be a word. Often it is. I need to write it down, because I have learned that it is some "divine" inspiration, and I don't know the importance it holds yet, whether it will become a painting, a poem, a story, a book. I just know it means something. Other times it will be in a dream, but one from which I awake, knowing I must write it down.
My waking hours are the same. I am often in my own world, and having been divorced for nearly 8 years, and having the luxury of living alone, I find it makes me more of that "different, unique" person I have long been told I am.
I'm almost to the point where I am no longer fit company for any living being -- often myself!

But I thank God every day that I was blessed (and cursed) with my way of feeling and seeing things.
Now if I could just translate them to the canvas successfully!
