One of my favorite rules is: Keep It Simple Stupid! I am often guilty of analyzing a passage or even a written performance instruction to death.
This also reminds us that simplicity is the beginning of expression. We should project the central idea or line and then all else becomes secondary. Playing too many important things makes for a cacophonous mess, or is simply a case of lazy playing. Think about the single most important element and make sure that is clear first.
Many editors also will suggest elaborate fingering schemes which add unnecessary layers of difficulty to otherwise simple passages. I am not nearly smart enough to remember all of this fancy finger dancing so I always choose simple, easy to remember fingering patterns.
