"Even at best talent remains a constant, and those who rely upon that gift alone, without developing further, peak quickly and soon fade to obscurity."
I feel this quick is very true because if one isn't always sharpening and tweaking their skills as an artist they don't progress and don't get better and they soon lose their talent
"Given a small kernel of reality and any measure of optimism, nebulous expectation whisper to you that the work will soar, that it will become easy, that it will make itself. And verily, now and then the sky opens and the work does make itself."
I think that this is all inspired by hard work and a good idea that you run with. This also come about with no judging of your own work and taking risks when working. With all these you can't fail when making a piece of art.
"If you think good work is somehow synonymous with perfect work, you are headed for big trouble. Art is human; error is human; ergo, art is error. Inevitably, your work will be flawed."
I believe this to be true and that we as people can't help but to make mistakes when doing art or anything at that. I think for myself i get bogged down on details and i don't just look at the big picture. I try and make everything perfect which inherently won't happen or work.
