If wisdom is worth thinking about, it is worth having. Wisdom goes beyond being smart, intellectual, and/or knowledgeable. Wisdom is the sum total of all of these and yet is only available to those who recognize this fact. The following was gleaned from Psychology Today online:

Wise people generally share an optimism that life’s problems can be solved and experience a certain amount of calm in facing difficult decisions. Intelligence—if only anyone could figure out exactly what it is—may be necessary for wisdom, but it definitely isn’t sufficient; an ability to see the big picture, a sense of proportion, and considerable introspection also contribute to its development.

The Bible speaks often and well of wisdom:

If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. James 1;5 NIV

Blessed are those who find wisdom, those who gain understanding, Proverbs 3:13

Get wisdom, get understanding; do not forget my words or turn away from them. Do not forsake wisdom, and she will protect you; Proverbs 4:5

Where there is strife, there is pride, but wisdom is found in those who take advice. Proverbs 13:10

For wisdom is more precious than rubies, and nothing you desire can compare with her. Proverbs 8:11

And then there is the age old adage: Early to bed, early to rise, makes a man healthy, wealthy and wise. Whether or not you place much stock in this verse, it is wise to consider the worth of wisdom.
