Leave your phone at home and go walk for 1-2 hours. You get a little exercise and as long as you're just cruising along level ground then you can space out for long stretches.
I love these bike rides and do a lot of thinking. But it’s not the same as when I was a kid and daydreaming and I’m not sure why.
Maybe my mind is just more structured? So rather than meandering I end up think about more introspective/pragmatic things?
Or maybe I’m just crazy!
