Not much to add after this (the very first answer).Most people want to start being creative long before they are ready, and long before they understand where it is appropriate and more importantly, where it is not.
At some point, I started creating things and replacing one quite automatic solution for many dubious solutions. Bad idea. The project should be quite perfect before the construction. I was spending all the resources in weak buildings... no project.
But I also believe that everyone can run a few experiments (which also requires some skill). Not creating mistakes, but testing hypothesis (concepts, principles...).
