Committing to building one brick at a time, one step at a time, consistently reaching out to one listener, one reader, one customer, and gradually expanding is the key to success. While it requires significant commitment to persist in one direction, it is crucial as the audience rejecting your work may not understand your vision or the progress you are making. Rejections are often based on various reasons unrelated to your work's quality or direction, hence staying focused and steady in your efforts is essential to overcome challenges and succeed in the long run.
