The Paper Boat Poet keeps the paper because it serves as a tangible connection to their creative process and the stories they wish to share. The paper represents the physical manifestation of their thoughts and emotions, providing a medium for expression and preservation of their work. This act of keeping the paper is a testament to the poet's dedication to their craft and the importance of their words.

The reasons behind this practice are multifaceted. Firstly, the physicality of the paper allows the poet to engage with their work in a tactile and sensory manner. The feel of the paper, the weight of the pen, and the act of writing itself can be deeply satisfying and meditative. This sensory engagement can enhance the creative process and lead to more profound and meaningful poetry.

Secondly, the paper serves as a tangible reminder of the poet's journey. Each piece of paper can hold the story of how the poem was written, the emotions that were poured onto it, and the experiences that inspired the words. This can be particularly comforting for poets, as it provides a sense of continuity and a way to reflect on their growth and development over time.

According to a study by the University of British Columbia, the act of writing by hand can improve memory and cognitive function. This suggests that the physical act of writing on paper may not only enhance the creative process but also contribute to the poet's ability to retain and recall their thoughts and experiences.

Furthermore, the paper boat metaphor itself is rich with symbolism. The paper boat represents the poet's journey through life, navigating the currents of experience and emotions. Keeping the paper is akin to keeping afloat on this journey, ensuring that the poet's stories and reflections are not lost or forgotten.

In conclusion, the Paper Boat Poet keeps the paper due to the tangible connection it provides to their creative process, the emotional and symbolic significance of the paper boat metaphor, and the cognitive benefits of writing by hand. The act of keeping the paper is a testament to the poet's dedication to their craft and the importance of their words.
