Final answer:
The Lady of Shalott believes that knights are not worth the trouble to have in the lives of maidens, but this is false.
Step-by-step explanation:
The Lady of Shalott tells herself that knights are not worth the trouble to have in the lives of maidens, which is false.
In the poem, the Lady of Shalott has been cursed to stay in her tower and weave, and she sees the world outside through her mirror. She sees knights riding to Camelot and decides that they are not worth the trouble because they bring death and destruction. This is shown in the lines, 'The knights come riding two and two; She hath no loyal knight and true, The Lady of Shalott.'
