Did you ever miss a shot because you forgot to cock shutter?
I've missed shots because I've swapped lenses while someone asked me a question during event setup, forgot that I hadn't yet taken the cap off the new lens (but remembered going through metering, white balance, and initial test shots) then raised the camera to frame something and quickly discovered my error...
New tools mean new and different ways. Learning all the tools you have at your disposal and then selecting the one you want for a job is pushing your creativity. Deliberately ignoring other tools and processes completely isn't creative, it is being willfully ignorant of options and potential in my view.
