External Influences of Motivation
The Incentive Theory suggests that people are pulled toward behaviors by rewards (incentives).
Extrinsic (external) motivation is any influence comes from an outside source. An intrinsic (internal) motivation is any motivation comes from within and provides a sense of satisfaction. Incentives can provide negative motivation, a promise of an unpleasant outcome, that can be avoided if a specific behavior is performed.
Decisions are not made in a vacuum. There are various external factors or influences that affect how we function, our objectives, and short and long term strategies.
A major factor that affects us is the number and degree of obstacles that may prevent the successful implementation of a decision.
