Happiness is not something you can obtain securely, it is something you can experience in the moment of a never-ending flow of time, which is subject to change. Outer (physical) change can be expensive and may not be easy to do, however, inner change can be done in a split sec.
The Declaration of Independence guarantees the right to "life, liberty and the pursuit of happiness" Remember, wise men put "The pursuit" in there for a reason.
<Happiness is a state of contentment that is often conditional and subjected to change. On the other hand, Peace is a state of inner calm that the individual achieves which is not subjected to change>
