My dad is one of the most disorganized people I know. His desk is layers and layers of receipts and papers. (Side note, my dad is a plumber, not a web developer.) I grew up always having a messy desk too. A few years ago, I realized that I work better when I have less clutter on my desk.
Knowing this has helped me in so many ways. Organizing my desk is now a part of my process and is one of the ways I get into the zone.
A clean desk gives me more room for creativity.
