Projects Participation in the work of the nonprofit organization Clean Memphis, which aims to “make Memphis the cleanest city in the country” (cleanmemphis.org), is an example of what motivation psychologists call a personal project. Personal projects consist of a set of actions that are organized for a common purpose and that extend over a significant period of time. In the Clean Memphis project, participants take part in a set of activities (street cleaning, environmental education, identifying violations of environmental laws) that contribute to the overall aim of a cleaner city.
