The Best Revenge?

Something interesting i read recently.

"The best way to get revenge at someone, is by living a happy life"

Kinda makes you think doesn't it?  Instead of having malicious thoughts of violence, just continue living a good life.  A good happy life.  This does bring up a question though.

1. Is it important for that person to see you living this happy life in order to fulfill the revenge?  Make them regret and pound their chest with anguish? 
2. Must you forget about the thoughts of revenge to live a happy life?
3. Does your happiness need to be larger than the other person?

I sorta understand what it means - yet it's confusing when you ask the above questions.

This all came about after watching a Korean drama called 남자 이야기 (Man's Story) aka Slingshot.  The story resolves around revenge, but the protagonist is this really "nice" guy that is portrayed to be too much of a saint.

For example, he is betrayed by his lover as she goes off and marries his enemy (the one that killed his brother) - yet he still worries about her and helps her.  It was so frustrating watching this ridiculous fiction.  I wanted to bash the monitor!

This drama put a bitter taste in my mouth.  Crappy ending.  I would have preferred a total victory from the protagonist.  With the psycho business man losing all his money and living in a shack eating trash for dinner, and his betraying wife following him around with a shopping cart.  I feel so cynical right now.. haha.  Freakin drama's making me think...
