I don't focus on happiness as a goal or an end.
Live with the objective of being happy.
The great end of all human industry is the attainment of happiness
I do explore the emotion every once in a while. I'd like to think you don't stop being creative once you get happy. My ultimate goal is to end up being happy. Most of the time.
It's OK to have a plan, to invest in your future - for your financial security, your love life, your personal fulfillment, and even your happiness. To have personal happiness as a stated goal doesn't detract from it if you get there.
All opinions in the world agree in this, that pleasure is our end, although they differ as to the means of attaining it.
The miracle-minded perception would be to make happiness itself our goal and to relinquish the thought that we know what that would look like.
