In modern life, instead of people growing "older and wiser," people can simply grow older and older. People can live longer and longer without becoming any wiser for it.

How can we think about getting upset in a manner that might bring a level of serenity to our lives? The key is, I think, that we need to be responsible for what upsets us.

We can easily end up spending the last half of our lives wrestling with the paradox of "How old I am isn't how old I feel!" I believe this internal conversation about "How old I am" versus "How old I feel" serves a purpose.

In our society, we hope that wisdom comes with age. What we don't expect is for increased energy to also be a component of our golden years.
