The lesson I learned…
You must have played a part in whatever went wrong. Figure it out. Find your fault.
Something didn’t go as planned.
A mistake was made.
All mistakes are avoidable.
What role did I play?
How did I contribute to things going wrong?
What could I have done differently?
How could I have avoided it?
What should I have done differently, and more importantly, why didn’t I do it?
