Self Improvement through motivation

In order to be happy and satisfied, one needs to be motivated. Motivation basically gives us the hope to look ahead and dream higher. It is the force that propels us to go ahead. But why do we need to change? People change for various reasons. Some change because they don't want to face the pain in their lives. Some change because they are sick of their failures. For instance: poor grades can make us realize the importance of hard work while studying and can motivate us to change. Similarly, debts can make us look for other jobs or to do more than one job.
