The answer is a desirable outcome. In an approach-approach, the individual is faced with the necessity of making a choice between two (or more) desirable goals. Since both goals are desirable, this is the least worrying situation. "Shall I fly or take a boat to Europe?" might be easily determined if both means of travel are seen as pleasurable.
