How does not fail work?
What parameters are used to rate who isn't failing and who is?
Does not failing make the man invincible?
When and how do you know you are not failing?
Does it feel good?

I am not sure what these answers will be but I am most certain that, someone somewhere has written a book about these questions without having to be on either side all their life.
Okay, maybe they have at some point in their life, but does that make them an authority in the matter?

When I interact with people, I get a sense of feeling that, failing is not really what is the matter with many but, their inability to understand what they really are made of.

Many have the capacity to be more than just "ehn", but they never really get off the ground to spring forth into the unknown.
Now, I find myself wondering... How does it work?
