Some say creativity and imanation are talents which gets developed over a long time of practice. Im not a writer and but a photographer. Before I started, it was inherently difficult especially when I was learning how to use photoshop. But now I can teach someone how to use the software without a computer. I believe imagination is likewise
Photography is a skill - it is possible to have an eye for the image, but not the skill to capture an image. Similarly, it is like me being able to hear when a note is off tune, but not be able to sing myself.
Very funny. I'm very much like you. Trying to sing all my life but was never able to get the tune right.
