Annie Dillard, in her book "The Writing Life," emphasizes the importance of fully investing oneself in writing. She advises writers against holding back their best ideas for later use in a book or for future projects. Instead, she encourages them to "give it all" right away and to express their thoughts and creativity without reservation. This notion of not hoarding creativity stems from the belief that more inspiration will come when you share what you have.
Dillard's perspective suggests that the act of creating is a dynamic process, fueled by the willingness to take risks and to share one's work in the moment. The idea is that writing is enriched by continual flow and spontaneity. The metaphor of well water signifies that creativity is abundant, and by spending your ideas freely, you open yourself up to new and potentially better ones that will emerge in the future.
