Why People DON'T do what YOU want them to do

There are a myriad of reasons why people DON'T do what YOU want them to do, but we may be able to break it down to two main factors :
1. Motivation and drive
2. Values and priorities

The first one is simply based on a more emotional and psychological level - perhaps the person does not feel like doing what you want them to do. This could be because of their state of mind or the nature of the motivator. It could be your own behaviour affecting their state and emotion as well as others and the environment/situation/mood/circumstances. This also ties to the second factor (they are not completely independent): the values and priorities someone has may not be in line with yours, usually falling onto the the individual's logical or rational side. Everyone has a different take on what is important to them at any time or period of time. These may change but they are not always in line with what your values and priorities are.
