It's a metaphor.

This is the kind of loser I am . . .

I swing . . . I make contact . . .

Then I always try something that I NEVER try . . . do more than I can do . . . be more than I can be.  To accomplish something that I have never accomplished before.

And I fail.  And I fall.

Down.  Embarrassed.  Humiliated.  Mortified.  Crushed.  Exposed.

And all the time . . . . . I knocked it out of the park.  

It's a metaphor.
