Kill injured monsters first

The real world may not have druids and paladins, but it’s chock full of monsters. They’re called “term papers” and “errands” and “mysterious car problems.” [T]here may be one monster that looms larger than all of the others, who clearly needs to be attacked. But before you do, look around for injured monsters — the half-finished tasks that probably need only a few more minutes to complete. If you don’t deal with them now, they’ll be a constant distraction, and may eventually come back stronger.
