I've been using GCal to schedule 15 minutes of writing each day. Sometimes I keep going beyond the 15 minutes, but it's good to have that routine in place to keep me at it

Analog items: A great task lamp like the Anglepoise Type 75 https://www.anglepoise.com/collections/type-range/type-75 It's a classic. Turning it on puts me into writing/working mode. I also have a record player right next to my desk, and on the turntable is a Grateful Dead live album. The side it's on ony has two songs, but they're each like 15 minutes long. When I'm about to start writing, I play it. It's like walk-up music. https://www.youtube.com/watch?v=luAqu8VX5wo
