"S'all Good, Man."​

"Perfection Is The Enemy Of Perfectly Adequate."​

"Money Is The Point!"​

"I Travel In Worlds You Can't Even Imagine."​

"Say Nothing, You Understand? Get A Lawyer!"​

“Confidence is good. Facts on your side, better.” ​

“Facts are facts.”​

“Sometimes the good guys win.”​

“I’m not good at building shit, you know? I’m excellent at tearing it down.”​

“Money is not beside the point… Money is the point.”​

“Whoa, whoa. Hold up. What the hell happened to you? I get it, the first rule of Fight Club, right?”​

“A good magician never reveals his secrets.”​

“Got to look successful to be successful.”​

“The lesson is, if you’re gonna be a criminal, do your homework.” ​

“If I had to do it all over again, I would maybe do some things differently. I just thought you should know that.”​

“Some men aren't looking for anything logical. They can't be bought, bullied, reasoned or negotiated with. Some men just want to watch the world burn.”​

"Ernest Hemingway once wrote, "The world is a fine place and worth fighting for." I agree with the second part."​

“There’s no better way to destroy someone’s life than to uncover their secrets.”​

“Hackers are breaking the systems for profit. Before, it was about intellectual curiosity and pursuit of knowledge and thrill, and now hacking is big business.”​

“Hackers often describe what they do as playfully creative problem-solving.”​

“Computer hackers do not need to know each other’s real names, or even live on the same continent, to steal millions in mere hours."​

“While many hackers have the knowledge, skills, and tools to attack computer systems, they generally lack the motivation to cause violence or severe economic or social harm.”​

“Very smart people are often tricked by hackers, by phishing. I don’t exclude myself from that. It’s about being smarter than a hacker. Not about being smart.”​

“At the end of the day, my goal was to be the best hacker.”​

“Humiliation is the favorite currency of the hacker.”​

“The hacker didn’t succeed through sophistication. Rather he poked at obvious places, trying to enter through unlocked doors. Persistence, not wizardry, let him through.”​

"Rules. Without Them We Live With The Animals.”​

“Consider This A Professional Courtesy.”​

"I've Lived My Life My Way, And I'll Die My Way."​

"You stabbed the devil in the back, and forced him back into the life that he had just left."​

"You Want A War, Or Do You Want To Just Give Me A Gun?"​

"Leave one wolf alive and the sheep are never safe."​

"When you play the game of thrones, you win or you die. There is no middle ground."​

"It's not easy to see something that’s never been before: A good world."​

"I believe in second chances. I don't believe in third chances."​

"If you only trust the people you grew up with, you won't make many allies."​

"A man with no motive is a man no one suspects. Always keep your foes confused: If they don't know who you are, what you want—they can't know what you plan to do next."​

"Never forget what you are, the rest of the world will not. Wear it like armor and it can never be used to hurt you."​

"I try to know as many people as I can. You never know which one you'll need."​

"It's hard to put a leash on a dog once you've put a crown on its head."​

“Everything before the word ‘but’ is horseshit.”​

“A lion doesn’t concern himself with the opinions of a sheep.”​

“Nothing FUCKS you harder than time.”​

“You pray for rain, you gotta deal with the mud too. That’s a part of it.”​

“I’d be more frightened by not using whatever abilities I’d been given.”​

“Luck is where opportunity meets preparation.”​

“If you have an enemy, then learn and know your enemy, don’t just be mad at him or her.”​

“Every failed experiment is one step closer to success.”​
