"Implementation Intentions"

A very basic idea, implementation intentions are the processes by which you or I will go about attaining our goal/s, or a way that we'll respond when a certain condition happens.  Just spelling out your intentions helps to make them more concrete and increases ease of attainment.  Instead of drinking when invited to a bar, for instance, you might make a decision to always redirect the invite to a restaurant, or some other venue where there are other options besides alcohol.  This helps us to stay on track when immediately available by unhealthy options exist, like fast food as well.
