Pratchett did start the series with a loser protagonist, Rincewind, before pivoting to mostly competent main characters.

Even then, he goes through the typical heroic arc of:

1) Starting the story by Resisting the Call to adventure -- in a way that reveals strong character motivation (a strong desire to live)

2) He suffers a series of trials that slowly push him to the opposite view: That he must act boldly and selflessly if he is to survive (and thereby also save the Discworld)

3) He performs a heroic act (even if only armed with a "half-brick in a sock") contributing to the good side's overall victory

Although to be fair, he does tend to revert by the start of his next story.

		> Although to be fair, he does tend to revert by the start of his next story. I'd say that's most of the Discworld series though. Protagonist is living peaceful, MacGuffin ensues chaos, Protagonist (or Arbitrary Thing) saves the day, the Disc goes back to normal, and the Turtle continues to move. Discworld is my favorite series and I think Hogfather and Feets of Clay should be mandatory reads for people going into AI.
