Spot on. Most of these could be two small words of "I Need" also. It's all based on the perception of what the individual feels they want/need to be happy and can't live without.

I feel most individuals forget that happiness isn't defined by how much we keep obtaining and what we want to have but being content with what we currently have and what we have obtained. Yes we should strive and work towards what we want but it isn't obtaining it that brings happiness that lasts. It's the work put into getting the want that leads up to it that brings a sense of accomplishment and happiness.

As a whole we are never fully satisfied if we have nothing we are working towards. We always "want" more and have a hunger to obtain everything from knowledge, different forms of companionship and materialistic possessions.
