It became an anchored daily practice that I could start hanging other practices on. If I wanted to develop some other focus or habit, I could just plan to do it before or after a meditation session. And that regularity gave me space for really intentional skills building and habit development, which I had always struggled with.
It also meant I had two anchors in my day where my mood and mind and body could find some kind of center. Again, the precise impact wasn't the same everyday, but it provided a check against things spiraling away like they sometimes can.
And then the other lovely benefit is that it left me needing less sleep at night. I don't nap during my meditations (or very rarely, anyway) but they seem to provide an early down payment against my sleep needs, and so I ended up ahead on total waking time. For 40 minutes of meditation spread throughout the day, my night time sleep needs dropped by an hour or two. It took me a while to realize this had happened, but it did and research seems to confirm the phenomenon. I'm not a Type-A Go Go Go person, but it's nice to have a little extra time in my days!
