   Little steps are often the hardest to take. 
We are too used to making leaps in the face of 
adversity, that a simple skip is so hard to do. 
We should all learn to walk soft, walk small, 
see the world around us rather than zoom by it.

"Innocent, unbiased observation is a myth." --- P.B. Medawar (1969)
