Happiness....

What is happiness, and why can't I seem to find it? Webster defines it as :

Main Entry: hap·pi·ness

Pronunciation: \ˈha-pē-nəs\

Function: noun

Date: 15th century

1 obsolete : good fortune : prosperity
2 a : a state of well-being and contentment : joy b : a pleasurable or satisfying experience
3 : felicity, aptness

So in definition one it says obsolete... when I looked that up it says it means "no longer in use, old fashion"... so what Webster is telling me is that happiness is no longer an option... no longer used... hmm, seems like I'm doomed....
