Improvement - Perfection - Degradation
Re: skill levels
I think many of us go through learning curves where we can see major improvement from "where we were" as compared to " where we are now".
Then there is "perfection" - which one can sometimes get quite close to -
Then - for many of us - our physical conditions cause degradation of our motor skills - and we simply are not able to do things at the same levels we once could. Frustrating!
So when evaluating a project ( other than in an exhibition), think of where the person is on the curve.
