This is an example of how his decision affected his goal. Adam had a clear goal, which was having $4,000 saved by the end of the year. He also had a clear way to get there by putting $150 in his savings account. Therefore, the goal and the plan were designed in an effective way. The problem Adam had, however, was sticking to his plan. He made a wrong decision, which was spending too much money at the mall. Therefore, because of this decision, his goal has been affected as well.
