Seth Godin has a wonderful post today entitled Next. In it, he asks people to think of whatever work task they been assigned not as their "next" job but, instead, as their last. (In the sense that it will be the last time they ever do it.)
If a person approaches a task from this new perspective it will almost ensure that it isn't the last time they perform that job because the person will likely produce a much higher quality product because they didn't just "dial in" the assignment.
I encourage you try this approach next time you are assigned to write an article, make a presentation, train a new employee or meet with a potential customer.
Sometimes gaining a new perspective is just unlearning an old one.
