Motivation

This image is often associated with motivation. It shows a donkey that is motivated to pull a wagon in order to reach a goal, the carrot. Unfortunately for the donkey, it doesn't realize that the goal is unattainable, but it is enough motivation for the simple beast. We often need motivation to do things that we are unwilling to do. These can be shaped by our desires and needs, depending on what we want at the moment, and it can come in many forms, including food.

Motivation - A need or desire that energizes and directs behavior.
