The home office change that mattered more than any furniture I bought

I spent real money upgrading my desk, chair, and monitor before noticing that the single change that actually improved my focus the most cost nothing: moving my desk to face a wall instead of a window overlooking the street.

The window felt like the obviously better choice — natural light, a view, something to look at during a thinking pause. In practice, every passing car and person became a tiny, involuntary interruption, dozens of times a day, each one small enough to dismiss individually and large enough in total to genuinely fragment focus across a full afternoon.

Facing a plain wall removed that entire category of interruption at zero cost, before I'd spent a cent on furniture. I still don't fully trust how much of my focus problem turned out to be a window, but the difference was large enough that I haven't moved the desk back.
