Aristotle's definition of Happiness

Read the selection from Aristotle's Nicomachean Ethics and write a 1-2 pg. response . How does Aristotle define happiness? How does he distinguish his definition of happiness from other possible definitions? What do you understand by the term "happiness", and how is this different from Aristotle's conception? Do you think that Aristotle's usage of the word is different from (or similar to) the way in which "happiness" is typically used today? Explain.
