I think it was Oscar Wilde that said that happiness is not an event ( in the moment ) but rather a memory. I kick that idea around when I'm doing housework. Define happiness, please.
I think that happiness is when you have found your 'real' inner person. Because, it changes how you see everything around you. You have the where-with-all to handle your affairs as well as most of the people around you. Life became a joy and not a job!
I consider happiness to be a feeling of joy and significant pleasure that lasts at least 8 seconds. I could also consider it to be contentment plus mild or sporatic peasure over a longer period of time. I'd prefer if there were differentiating words. Maybe there are and I just don't know them.
