To look at life differently they could not be so bold
Some people don't grow wiser they merely grow old
They remain as they were and think in the same way
And the only change in them is they've grown old and gray
Wisdom is a thing that can serve one quite well
Though also a thing one cannot buy or sell
Financially well to do wise people one might say rare
For wisdom will not make you a millionaire
That the wise are a minority comes as no surprise
for many people grow older but they do not grow wise
No fool like an old fool you do hear some say
The truth in these words it is living today
They remain as they were and think in the same way
And they do not grow wiser only grow old and gray.
