I actually don't believe in "failure". It's become a weak construct that carries negative judgment with it. Originally, I suppose, it simply meant not getting what you wanted or attempted without the negativity. Just a matter of fact observation like, "I failed to get through to him on the phone."

Now the word "failure" is used in a way that connotes an element of shame or inadequacy. "I wanted to become successful, but, alas, I've failed."

    4.  Get Discouraged.
