What does happiness mean to you

I finally finished watching this movie called "Into the Wild".
Loved every bit of it and cried my heart out at the end. Brilliant Direction, Picturisation, Acting, and Music. And that this movie is based on the true story of Christopher Johnson Mcandless,
left me overwhelmed and speechless.

So, the protagonist of the movie, Christopher grows weary of the materialistic world and selfish human beings that surround him and added to that , he has had an abusive childhood with his parents always bickering.

Out of weariness, HE shuns the society, wanders into the wild, sails down the Colorado river to Grand Canyon, kayaks to Mexico, stays with hippies in Arizona , and, finally braves the great Alaskan adventure, all in the pursuit of happiness by growing closer to nature. He hitch hikes in nature , lives like the ancient human beings without any modern conveniences and money. He loves it thoroughly and finds some happiness in it.

He rediscovers happiness during the course of stay in Alaska. While he is in Alaska, he reads an excerpt from Leo Tolstoy's Essay on Family Happiness:

“I have lived through much, and now I think I have found what is needed for happiness. A quiet secluded life in the country, with the possibility of being useful to people to whom it is easy to do good, and who are not accustomed to have it done to them; then work which one hopes may be of some use; then rest, nature, books, music, love for one’s neighbor — such is my idea of happiness. And then, on the top of all that, you for a mate, and children perhaps — what more can the heart of man desire?”

After reading the last lines Chris smiles and decides to go back. Having lived many experiences in his lifetime , after having gained the wordly wisdom , he finally intends to return . It is the spring time and the ice caps have melted , thereby the heavy flow of river makes it impossible for him to cross. He is trapped in the wild nature and dies of starvation/indigestion caused by consuming wild flowers. Before dying he etches onto the wood, "Happiness is only real when shared" and sheds a tear in his helplessness ?

A tragic unexpected ending.
I was hoping that someone finds him in ill-condition and rescue him.

Anyways, this movie got me into thinking about my idea of Happiness.

Some find happiness in family,
Some in their work,
Most in money and fame,
A very few in service of less fortunate people,
And extremely few, in nature.

I am yet to discover mine .
