The heavens are not filled with hostility. The sky does not express a frown. When I look up I do not contemplate a face of brass, but the face of infinite good will. Yet when I was a child, many a picture has made me think of God as suspicious, inhumanly watchful, always looking round the corner to catch me at the fall. That "eye," placed in the sky of many a picture, and placed there to represent God, filled my heart with chilling fear. . . . Heaven overflows with good will toward us! Our God not only wishes good, he wills it!
I don't know much about the music business, but for just general advice for someone trying to create things, as simple as this sounds, I think the best thing you can do is constantly try to improve upon your work. Always focus on that first and foremost, and leave everything else (marketing, image) completely secondary. Obviously, easier said than done when you're trying to make a living, but if you can move along those lines and earnestly try to make things that you really enjoy it can only benefit you in the long run.
