The extract from the book "Fight Club" by Chuck Palahniuk.

Only two guys to a fight. One fight at a time. They fight without shirts or shoes. The fights go on as long as they have to. Those are the other rules of fight club.
Who guys are in fight club is not who they are in the real world. Even if you told the kid in the copy center that he had a good fight, you wouldn't be talking to the same man.
Who I am in fight club is not someone my boss knows.
After a night in fight club, everything in the real world gets the volume turned down. Nothing can piss you off. Your word is law, and if other people break that law or question you, even that doesn't piss you off.
In the real world, I'm a recall campaign coordinator in a shirt and tie, sitting in the dark with a mouthful of blood and changing the overheads and slides as my boss tells Microsoft how he chose a particular shade of pale cornflower blue for an icon.
The first fight club was just Tyler and I pounding on each other.
It used to be enough that when I came home angry and knowing that my life wasn't toeing my five-year plan, I could clean my condominium or detail my car. Someday I'd be dead without a scar and there would be a really nice condo and car. Really, really nice, until the dust settled or the next owner. Nothing is static. Even the Mona Lisa is falling apart. Since fight club, I can wiggle half the teeth in my jaw.
Maybe self-improvement isn't the answer.
Tyler never knew his father.
Maybe self-destruction is the answer.
Tyler and I still go to fight club, together. Fight club is in the basement of a bar, now, after the bar closes on Saturday night, and every week you go and there's more guys there.
Tyler gets under the one light in the middle of the black concrete basement and he can see that light flickering back out of the dark in a hundred pairs of eyes. First thing Tyler yells is, "The first rule about fight club is you don't talk about fight club.
"The second rule about fight club," Tyler yells, "is you don't talk about fight club."
Me, I knew my dad for about six years, but I don't remember anything. My dad, he starts a new family in a new town about every six years. This isn't so much like a family as it's like he sets up a franchise.
What you see at fight club is a generation of men raised by women.
Tyler standing under the one light in the after-midnight blackness of a basement full of men, Tyler runs through the other rules: two men per fight, one fight at a time, no shoes no shirts, fights go on as long as they have to.
"And the seventh rule," Tyler yells, "is if this is your first night at fight club, you have to fight."

What is self-improvement and self-destruction for you?

The question is rather difficult for me, because I haven't chosen yet the definitions for these concepts, I wanted to see others people's opinions. That's why I'll try to explain these words in few nouns.
Self- destruction: laziness, misappropriation of your own soul, drugs.
Self-improvement: love, silence, understanding.
