The proverbial 'they' always tell us in order to achieve we must first see what we desire.
I once had a small group of children in my circle time, and I asked them to close their eyes and tell me what they see. One would say, "Nothing, my eyes are closed." Another would say, darkness with pinholes of light, or just the color black, but always there are those few who see beyond sight into imagination. Those few that can paint a picture of hope, interest, and delight, with only their imagination. Kids hate to hear us say, when I was a kid... But, it's true. When I was a child, toys were few and if you didn't have an imagination you got real bored. We were prairie doctors taking chickens for pay, or sitting in boxes fighting pirates on the open sea. We climbed stairs hoping to find Jack and his magic beans. It was fun. On a drive in the mountains did you ever tell your kids the story of the Indian Chief who lost his loved child, Falling Rocks. He loved him so much he posted signs all over asking travelers for help. We'd point out the signs WATCH FOR FALLING ROCKS. The rest of the trip was passed in diligent silence while they hunted for a little lost brave. I talk with kids today and their play involves death counts and how many levels they have or lives they have left. Humph! Constructive future building. Like I said...it's all in how you look at it.
