“Adulthood isn’t an award they’ll give you for being a good child.”
Vorkosigan Saga, A Civil Campaign (1999)
Context: Adulthood isn’t an award they’ll give you for being a good child. You can waste … years, trying to get someone to give that sort of respect to you, as though it were some sort of promotion or raise in pay. If only you do enough, if only you are good enough. No. You have to just … take it. Give it to yourself, I suppose. Say, "I’m sorry you feel like that", and walk away.
As quoted in Elevator Music (1994) by Joseph Lanza
Context: I began to become an adult when I was 24 and got married and had children. That matures you, but I wouldn't say I was fully an adult until I was in my forties. The trouble with the whole adult debate is that if you're asking 18-year-olds to go out and fight wars for you then you can't deny them adult rights even though in sorts of other ways they wouldn't qualify until they were about 25. These days adolescence stretches much further into adulthood than it used to. There's no longer any encouragement to be mature.

The Game: Penetrating the Secret Society of Pickup Artists (2005)
Context: A man has two primary drives in early adulthood: one toward power, success, and accomplishment; the other toward love, companionship, and sex. Half of life then was out of order. To go before them was to stand up as a man and admit that I was only half a man.
