Not having a clear vision for the song can lead to a lack of focus and direction in the production process. It's important to have a clear idea of what you want the song to sound like before you start working on it.

Practicing regularly will help you develop your skills and learn from your mistakes. Getting feedback from other producers can help you identify areas where you can improve.
