It is sad to grow old but nice to ripen.
Maturity consists in no longer being taken in by oneself.
I believe the sign of maturity is accepting deferred gratification.
Your lordship, though not clean past your youth, have yet some smack of age in you, some relish of the saltiness of time.

One does not get better but different and older and that is always a pleasure.
Maturity is often more absurd than youth and very frequently is most unjust to youth.
The immature man wants to die nobly for a cause, while the mature man wants to live humanely for one.
Maturity is the capacity to endure uncertainty.

Where id was, there shall ego be.
Maturity is the time of life when, if you had the time, you'd have the time of your life.
