As soon as you concern yourself with the 'good' and 'bad' of your fellows, you create an opening in your heart for maliciousness to enter. Testing, competing with, and criticizing others weaken and defeat you.
Never stop testing, and your advertising will never stop improving.
Testing leads to failure, and failure leads to understanding
Love testing yourself more than fearing loosing
I'm not going to recommend recklessness but somewhere just short of it - testing yourself and proactively pursuing a rite of passage has become necessary because in western developed countries we've become very comfort-addicted.
