Is happiness a state of mind or being?

I had this thought on the train home last night. Is Happiness a state of mind ( at some moment ) or a state of being ( a long stretched out period ) ? I think it can be both, but if you ask me it is definitely more of a state of being. Happy people are stable people. Sure they've got their ups and downs but they are ultimately, positive people who see the glass as half full. I'm growing to be a more happier person and i am embracing it fully. Happiness to me, really is all about stability. I am such a drama queen and it's no news that my emotions run riot all over the place a lot of the time. It's made my life very eventful and very busy but i guess all i really want is to be in one mood all of the time. I want that mood to be content/prepared/calm. I used to be agitated/anxious/hopeful. That is the pits, let me tell you. Yesterday, i wrote 790 words towards ' Life insurance '. For once in my life as a writer i don't care how my work is received. You can hate it or love it but all that really matters is that i fucking wrote it and that it's finished. Of course, that's still ahead for me. I have so much editing i need to do and re-structuring as well. On top of that i have some new ideas for articles that i gotta write in the next few days. I hope you have a productive and STABLE Saturday! Also please check this out. It's my latest published essay about my personal discovery of what happiness means and it's not about being a movie star or a Nobel laureate. Turns out simplicity truly does reign...
