Motivation or Lack Thereof in an Individual

Discuss what exactly drives motivation or lack thereof in an individual. Explain the issue.

What can help to continue to motivate people? What are the challenges with this issue and finding what it takes to stay motivated? How do we go about finding the drive after the initial discussion? Does motivation come from within, or do we find it from external forces? Does age play a factor or influence an individual when it comes to motivation? Are physical attributes of individuals a contributing factor?
