Read Proverbs 4.
This may be the strongest admonition in the Bible to get wisdom, insight and understanding. Again, it is addressed from one generation to the younger. Note that this is not a religious call, nor is it optional. Three times we are told that such wisdom is life itself.
"Keep hold of instruction; do not let go; guard her, for she is your life." (v.13)
"For they are life to those who find them." (v.22)
"Keep your heart with all vigilance, for from it flow the springs of life." (v.23)
What are the action steps in my life that demonstrate a heart that is committed to wisdom?
1. My Words. (v.24)
The charge here to put away all crooked speech and devious talk. Lying and deception are the elements of a fool's communication. Sooner or later it will be discovered. Shame follows a fool as sure as day follows night. A person committed to God is committed to truth. Words are carefully spoken by those who keep their heart with all vigilance.
2. My Watch. (v.25)
The choices we make in our viewing habits reveal whether we are foolish or wise. A wise person is vigilant about what they allow their eyes to see. This is not referring to the casual glance but the "gaze" on things that displease the LORD.
3. My Walk. (v.26)
A person committed to wisdom is careful about the direction and places they go. Each step in life is a decision to obey God or behave foolishly.
Ken Taylor's paraphrase of 4:23 communicates the intent so well. "Above all else, guard your affections. For they influence everything else in your life."
