Happiness is a quality of life we feel everyone has a right to pursue. So much so that it’s written in our constitution. What we think of when we envision happiness has a lot to say about what we are using that right for.
We acknowledge that we have to meet life half-way. It is unconscious by means that this “half-way” we give, is merely our every day life, and nothing special.
