I've been growing into this recently.
Learning to be okay with no inputs and no outputs. Eliminate distractions. Step away from the stress. Just for a few minutes at a time several intentional times throughout the day.
Now I'm finding it bleeds into the regular parts of my day — waiting in life for something, walking into a crowded room, even a lull in conversation — the inner silence surfaces for just a moment.
I'm definitely a beginner in this space.
