This is so thought provoking and really good words to think on. The two fears are required if one wants to be successful. Like you said the ability for us to know when to apply these acronyms, will make life much easier for us.

Just like the words of Jude Blume,
"Each of us must confront our own fears, must come face to face with them. How we handle our fears will determine where we go with the rest of our lives. To experience adventure or to be limited by the fear of it."

So it's very obvious that fear must come but the ability for us to confront them with either of these ways you've stated, will make us either a coward or a hero.
