The personal project is proposed as a new unit of analysis for the study of personality in its social, physical and temporal context. A sequential model of personal projects is proposed in which the major stages of project inception, planning, action, and termination are described in detail and related to dimensions of individual differences. A new methodology for assessing personal project content and structure is introduced, including techniques for assessing interproject impact and linkages with values and actions. The relevance of a projectanalytic approach to recent issues in environmental psychology is discussed. It is proposed that personal projects methodology might serve as a coupling device between the fields of personality and environmental psychology.
