A "forecast" and a "goal" are different things. One, a forecast, is a prediction of a future condition or occurrence, usually based in no small part on historical data and adjusted for the current prevailing conditions, while the other, a goal, is something that it to be achieved by taking certain steps within your control to make it happen.
Does a grocery store control its traffic in its store? Actually, yeah, they can to a large degree, by marketing and promotion. Same with other retail operations. They adjust the marketing and promotion (taking certain steps) to make their goals happen. In expediting, no amount of personal promotion and marketing will create additional emergency freight for me to haul.
If I were to set a gross revenue goal, and have it be a realistic number, it would be nothing more than a forecast based on historical data and then be adjusted for the current prevailing factors. Unless I am in total control of finding my own freight, then any goal based on a forecast is simply a hope that I hit that goal, as what all it takes to achieve the goal is out of my control.
Instead, I closely monitor expenses and try to remain as profitable as possible. That's my goal and the factors involved in achieving it are totally within my control.
Couldn't have said it better myself.
