I tend to me more action-oriented so it's hard for me to slow down too. I got direction clearly once when I was not at home - so I was thinking of a change of venue - as you said you went on a hike. Somewhere different.For me, my inner voice sounds like a jack rabbit on Red Bull-- bouncing all over the place a million miles an hour. His voice sounds... the image that comes to mind is Master quieting the storm. He is quiet. Still. Calm. Peace.
I've learned to listen to that still voice through my life, and it has been a huge boon for me. But my inner jack-rabbit can be much louder a lot of the time, so prayer and meditation on subjects have now become staples of my spiritual life. But man did that mediative prayer take work to learn how to do! When I was younger, I found that other methods tended to work better-- like going on a hike out in the wilderness. Focusing my bouncy energy into climbing mountains calmed my mind to better hear Him.
That's good to watch for: the quiet, still, calm, peaceful voice.
