Well, for her Bachelor paper, Marta (who did Dutch Studies in the Netherlands) had to choose a writer of Dutch literature, and her initial choices..
A: comparing the style of Marga Minco with Sylvia Plath because she saw a lot of comparisons, despite different subject matters, and
B: writing about the film adaptation of one of Marga Minco's most famous books, to compare it with the original book
..were responded with a simple "a lot of people wrote about this person already".
Later she ended up with a figure (the poet Judith Herzberg) she didn't even know yet -and the interest in the person didn't match her earlier choice-, so it felt kind of forced. Thus is was less easy to work on. She had to write about this person because "not many people wrote about her yet".
However, it wasn't that terrible because Marta herself could still choose which aspect of Herzberg's work to write about. She ended up writing about Herzberg's attitude towards language and communication and how she herself used words and language in her poems to emphasize her point.
