Happiness is elusive and temporary-an emotion, like many, that comes and goes depending on the situation. Success is in the eye of the beholder-what one considers successful, another would scoff at.
For instance, many people in all cultures are driven by success-it is the dream to be successful-expensive car, home, position, money-all material substances (except position), which can be wiped away by any tsunami or hurricane, a raging fire, flood, etc.
If one does not fall into the category of having a home, a job, or perhaps professional degree he or she is labled a failure. Or, at the very least 'unsuccessful'.
But, there are many circumstances which prevent someone from measuring up to the standards deemed by society. That, in itself, does not make someone unsuccessful.
To me success is measured by the person you are, how you exhibit the light of love and truth.
Happiness or success? How about-contentment. Contentment for being just who you are, knowing yourself and presenting that Self to the world in the highest regard. That is both success and happiness.
