‘I had a fixed purpose when I put to sea.
As I sat in the boat with my band of men,
I meant to perform to the uttermost
what your people wanted or perish in the attempt,
in the fiend’s clutches. And I shall fulfill that purpose,
prove myself with a proud deed
or meet my death here in the mead-hall.’

Beowulf, Seamus Heaney (trans.)

Lines 632-638: Beowulf has clarity of mission, is intensely focused and has commitment to the utmost. He tells Wealtheow he came with the purpose of fighting the evil demon Grendel. In this battle between he is prepared to fight to the death.
