Human error is the thief of human
happiness and the slayer of dreams,
careers, potential, and all too frequently
– life itself.
Viewing it as anything less hostile is to
willfully expose your throat to the knife.

Mature Self Assessment
Can I objectively see and accept responsibility
for my weaknesses and mistakes?
What don‟t I know that I need to?
What skills don‟t I have that I need?
How do I learn from my mistakes and make
less / „better‟ mistakes tomorrow?.
