One note I'd like to add is pay attention to your lighting, have a special "work-mode" set of lights that you turn on when you work and then turn off when you are no longer working.
I use the same work desk for non work stuff, but I turn off my "office lights" and it's a completely different vibe.
Everyone's tastes will be different but as for me, these are my preferences:
- Office lighting: at least 20k lumens of 5000K light with high CRI. For me I like to approximate the brightness of daylight. It's especially useful during the cloudy days of winter. My office is in a basement so the cheapest way to do that is string lights (like for outdoor patios), but with high quality LED bulbs.
- Personal lighting mode: regular house lighting, 3000K (so skewing towards a more yellowish, incandescent-like light). I still enjoy high CRI because I can't stand things looking bland but that's less important. More spot lights, less ambient light.
