Seth Godin says:
If you’re eager for change, every bit of information and every event represents an opportunity to learn, to grow and to change for the better. You hear some advice and you listen to it, consider it (possibly reject it), iterate on it and actually do something different in response.
On the other hand, if you’re afraid of change or in love with the path you’re on or focused obsessively on your GTD list, then incoming represents a distraction and a risk. So you process it with the narrative, “how can this input be used to further what I’ve already decided to do?” At worst, you ignore it. At best, you use a tiny percentage of it to your advantage.
