I have this, and I'm not a coder. I started life as a designer, working on mobile campaigns and the similar. When I came out of this "constantly sit in Photoshop" mode, I found it really hard to work. In a management role its impossible to have a "zone" thats comparable to my Photoshop days.

I beat myself up because sometimes I don't feel like I'm working hard enough, whereas what I actually think is happening is my brain has associated "working hard" with being in "the zone" - something I find hard to do with this type of work.

I'm currently sitting in Photoshop doing some logo resizing for our homepage, and its nice being "back in the zone"!
