Happiness is strictly mind over matter, people and events. The dictionary may say it is a state of bliss, fortune, etc., but like any other state of being in this life, it is extremely hard to be accurate as to exactly what it is. But one thing you can say for sure is that happiness does not last. A few negative thoughts or unpleasant circumstances wipe the happiness right out of your mind. I believe that there cannot be any long term happiness. Could you be happy every second of every day for a whole week? If possible, you would be smiling or laughing sixteen hours a day (can you be happy while you sleep?). We humans are subject to many events, mainly leading to unhappiness and very few towards happiness. Religious believers hope to be happy constantly in Heaven, but not in the physical body. You cannot be happy with your physical body, because of gray hair, toothaches, etc.

Happiness is strictly only produced by your brain (mind over matter). Your attitude determines how happy you are. Your house could be on fire or you could be very sick physically and you can still be happy. Any questions?
