“Most hackers are young because young people tend to be adaptable. As long as you remain adaptable, you can always be a good hacker.”

“Young people have a marvellous faculty of either dying or adapting themselves to circumstances.”

“In fantasy the world is always adapting to you, in reality you are always adapting to the world. That is the only difference.”

“And the most successful people are those who accept, and adapt to, constant change. This adaptability requires a degree of flexibility and humility most people can't manage.”

“People adapt. People change. You can grow where you're planted.”

“When you are young, you think that the old lament the deterioration of life because this makes it easier for them to die without regret. When you are old, you become impatient with the way in which the young applaud the most insignificant improvements … while remaining heedless of the world’s barbarism. I don’t say things have got worse; I merely say the young wouldn’t notice if they had. The old times were good because then we were young, and ignorant of how ignorant the young can be.”
