Your submissions are quite true @nancie. Everyone who desires to be great in life need to condition their minds to begin to dream again as it once did when we were much younger.
Our younger minds had no respect for reality. It had no capacity to see boundaries or impossibilities.
That was the mind that saw you as a doctor, sailor or a pilot.
Today however, we've given all that up because our "more experienced" mind which suddenly started accepting the realities of life has overshadowed our younger minds.
But whatever it is we can see, if we can see it long enough, we can become it whether a doctor, tailor or sailor.
We should never allow these "realities" to hold us back. They were there when we first dreamed and believed in our dreams. Just that we didn't see them.
