Every time I create something, whether an idea or a work of art, initially, its supposed completion seems absolutely perfect to me. However the more I think about it, stare it down, the more it marinates in my soul over the hours, days, and weeks, the more flaws I start to find in it; and finally, the more I'm pressed to continue enhancing it. It essentially turns out that whatever thing a flawed and imperfect, human eye once thought was amazing begins to appear quite wretched. This is why, eternally, God cannot be impressed by mere talents or by mortal achievements. To perfect eyes, I imagine that great is not really that great; rather, humility is ultimately a human being's true greatness.
There are enough ideas, images, symbols, and experiences in your head already to work with for a lifetime. It's a little like having a car with an unpredictable battery, though. Sometimes you get in and it starts right up. Other times, especially if it has been sitting idle for awhile, you turn the key and nothing happens.
When you draw, you copy the world don't you? You remake it on paper, but it isn't the same. It's yours. No one else could have created it just like that. When I make poems, I use the words we all use, but the order and the sound create a new power. This wood is someone's creation. We stumble through it's tendrils, as if we're crawling through the synapses of his mind.
