Slip is Not a Fall

A slip is a single event, a one-time reemergence of an unwanted behavior that need not lead to a fall or a relapse. A fall or a relapse, by contrast, is a complete abandonment of the goal and a retreat back into your old patterns of behavior.
 

When a slip happens, you can persevere, think optimistically and immediately recommit. In fact, slips can actually reinforce your resolve.
