"Happiness isn't something you experience; it's something you remember." Oscar Levant

First I found the quote above and then I found this:
"Nothing prevents happiness like the memory of happiness."--
Andre Gide
For obvious reasons, I had to include both in today's post.
Here's the flaw I see from both Andre and Oscar: their definition of happiness seems to require a certain event that you look back upon with longing.  
There is such a thing as unreasonable happiness, that which just springs from the day, as unquantifiable, unknowable, and completely ephemeral as every true emotion seems to be.  
You just feel. . .happy.  
It's definitely an "experience" (take THAT Oscar!) and (En Guard, Andre) it's not "a memory" of something in the past.
It just is, and it feels wonderful.
