Nope. Goals are fine things, but I believe in concentrating on what it takes to achieve a goal, not on the goal itself.
The article says, "The easier a goal is to see, the closer it seems." I believe the opposite is true. The closer a goal is, the easier it is to see.
Unrealistic goals, or ones out of your control, can be devastating, and few goals people set are as easy as saving for a vacation. "Vacation" shouldn't be the goal, anyway. Saving a certain amount of money each paycheck should be the goal.
When applied to writing, "I want to be a published novelist" isn't a goal at all, it's a dream, and one out of your control.
Today I will spend the hours from seven to nine P.M. writing is a goal, and one fully within your control. It' doesn't require visualization, it' just requires sitting down today and doing it.
Do this, and you give your long-term dream the best chance of becoming reality. Don't do this, and chances are the dream will always remain a dream.
