I love my Synology NAS. It’s the DS920+. I’ve had it for a couple years. I upgraded the memory to 8 GB and use Portainer for a docket UI. I have 24 containers running on my NAS now, including sab, radarr, sonarr, deluge, joplin, piped/hyperpipe, youtubedl, jellyfin, pihole, and lemmy. 8gb of memory and about 45% used. Plex also runs as a native DSM package.
My go to is counting backwards from 100. I typically time the counting with my breathing, and I try to slow my breathing. Most nights I’m usually out by the time I hit 80. If you find your mind wandering, try to bring your thoughts back to your Breathing. I started doing this after I had been meditating for a while, so it felt fairly natural. If you’re new to meditation, do some basic meditation training to get the idea. Most meditation trainings start with learning how to focus on your breathing.
