Everyone in the world is motivated by something.

Some people are motivated by a need to engage in certain actions. Others might feel a desire to earn a particular reward. There are also times when people are motivated to act by simply avoiding very specific problems or issues that might happen in their lives. It is vital for people in supervisory positions to understand whatever it is that influences and motivates someone to action.
 

The purpose of this book is to help understand what motivation is and the many theories that make up the science of psychology.
