At 20, the will reigns; at 30, the wit; and at 40, the judgement.

Aging is mandatory. Maturity is optional.

Age is a very high price to pay for maturity.
Youth is a disease from which we all recover.
It's sad to grow old, but nice to ripen.
It's not how old you are, it's how hard you work at it.
The older you get, the stronger the wind gets - and it's always in your face.
Women over thirty are at their best, but men over thirty are too old to recognize it.
There is still no cure for the common birthday.
