Do you know why people motivated?

When the motivation word is not there in managers' vocabularies, they motivated their employees what people called it by "carrot and stick". This word relevant to relationship between a human and a donkey. Donkeys will do something that people want after they has given a carrot, but is not reversely. By doing it, the donkey does not do anything, stick is used as a punishment. This situation is like a machine, so we can say a human is machine.
In human being, this situation can not stand for a long time. The human has feeling, perception, and heart. Therefore, researcher begin to identifify, examine, and make a conclusion about motivation. Finally, we have known that there are two classification of motivation theories.
1. Content theory - this theory aims to examine a question what motivate the people. this revolve around the identification of inward reward.The answer is need. All of people must have a need to survive in their life, such as physiology and psychology need.
We can refer to some scientist like Maslow, Alderfer, and Herzberg.

2. Process theory - this theory aims to examine a question why people behave as they do. Adam's equity theory is talking about this, incorporating such factors as perception and learning.
