One of the most important skills that a businessperson can have is the ability to look at your work and realize what needs to be changed. A creator can not be beholden to every concept that comes from them. The greatest directors know that a certain amount of what they shoot has to hit the cutting room floor. When you formulate a strategy, you must be able to examine your idea with an objective eye.
An alternative to this is to have someone you trust take the role. If you’re too close to the project, it’s always preferable to have someone else give you their opinion of how to trim the fat. So long as you listen to that person you will most likely be doing the right thing, even if it hurts to modify your work. Never underestimate the importance of a fresh perspective.
