Disabling all notifications where possible. Turning my phone off when I'm not expecting important calls. Books. Walks in nature. Cycling. Allowing for a small window of time at night for social media, then I move the phone into another room so I'm not tempted to refresh my feeds.
Unfollow, unfriend, unsub, etc. from what doesn’t provide any real value to your life. In otherwise minimize what you consume.
Being in nature
I ride my bicycle or motorcycle. You can't be online when your hands are busy.
I'll usually bring a book or a notebook, linger in cafés and parks, and browse random shops.
Turn off the electronics. Read books on paper. Write in a notebook with a pen.
