" I have a teaching job that allows me to pay the rent and affords me to, frankly, write the books I want to write. "
- David Shields

In simple terms, the speaker is expressing that they have a stable job as an educator which provides them with financial security sufficient to cover their basic needs such as rent. This financial stability allows them the luxury and freedom to pursue their passion for writing without worrying about immediate monetary concerns.

At a deeper level, this quote highlights the importance of having a steady income source that enables one to focus on creative pursuits or personal interests outside of work. It suggests that while the job may not be directly related to the individual’s ultimate goal or interest—such as writing in this case—it is essential for providing the necessary financial support and time freedom to pursue those dreams. The quote also implies a sense of honesty about why someone might choose a stable, less exciting career path: it serves an important role by freeing up resources needed to follow one's true passions without external pressures.
