Its interesting @Judi9877
Sounds like a phrase to cover the idea of confidence.
Knowing one would never fail is a little to all encompassing so my reality check alarm goes off a little.
Being a teacher I have a layered and developmental approach to life and learning.
It could make somone over confident and cause others pain.
Often the processing and whole experience is just as important as the achievement.
"Success and failure" is an overly dualistic approach to achievement in life, in my opinion.
Human endeavour seems more nuanced to me. As I started off as a maths nerd I might have been inclined to use percentages, but motherhood, music and working at the tax office put me off thinking in numbers, even computer binaries .... tho I know full well some people demand figures in the search for accuracy.. lol. Perhaps 1000 sculptures in 1001 shades of colour ...
