I wish I can tell you that doing creative work is easy. But it’s not. Beginning with the end in mind doesn’t always work.
Having a strict outline or plan for the project may not work for everyone. It doesn’t for me. I prefer to organise as I work through the project.
Beginning with the end in mind might not work for a creative project. But you can follow a 7 stage creative process even if it’s inherently nonlinear.
