A Guided Meditation
You can listen to the 10 minute visualization and write down or draw the things, symbols, colors or metaphors that came to and use any of these things in your map.
You should know that this is a 20 year ahead visualization, and that for the purposes of your map, you could pick one small thing that gets you closer to the vision you got.
I got a metaphor of myself being like a vine, spreading, blooming, with room to grow and fertile soil.
What imagery comes to you? If no imagery came, what did? A word? A feeling? You can always start where you are.
