I am not Aristole (who lived short period of his life, 384 to 322 BC),

But if I define 'Happiness' in my way, it's 'Contentment'.

In other words, 'Happiness' is when 'I Feel Good'.

Examples of The Moments of 'Feeling Good'

1. When I listen to the music while I'm driving Alone

         - and I see her on my screen
