Maturity is the capacity to endure uncertainty.

You grow up the day you have your first real laugh at yourself.

Maturity is the art of living in peace with that which we cannot change.

When you make a world tolerable for yourself, you make a world tolerable for others.

Growing up is after all only the understanding that one's unique and incredible experience is what everyone shares.

Smoking is, as far as I'm concerned, the entire point of being an adult.

I still want to play music but I don't want to look like Donald Duck while I'm doing it.

A child becomes an adult when he realizes that he has a right not only to be right but also to be wrong.

The mark of the immature man is that he wants to die nobly for a cause, while the mark of a mature man is that he wants to live humbly for one.

Maturity consists of no longer being taken in by oneself.

We have not passed that subtle line between childhood and adulthood until we move from the passive voice to the active voice-that is, until we have stopped saying It got lost, and say, I lost it.

When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.

When I was very young and the urge to be someplace else was upon me, I was assured by mature people that maturity would cure this itch. When years described me as mature, the remedy prescribed was middle age. In middle age I was assured that greater age would calm my fever and now that I am fifty-eight perhaps senility will do the job.

Tis but an hour ago since it was nine, And after one hour more 'twill be eleven; And so, from hour to hour, we ripe and ripe, And then, from hour to hour, we rot and rot; And thereby hangs a tale.

Grown up, and that is a terribly hard thing to do. It is much easier to skip it and go from one childhood to another.

A person remains immature, whatever his age, as long as he thinks of himself as an exception to the human race.

Maturity begins when you feel you are right about something without feeling the need to prove someone else wrong.

What we are is our parents' children; what we become is our children's parents.

One sign of maturity is knowing when to ask for help.

Marriage is our last best chance to grow up.
