True thanksgiving flows from recognizing God's goodness rather than accumulating possessions. Psalm 23 reveals that the Lord as our Shepherd provides everything we truly need. When we understand that we are known personally by God and that He prepares a table before our enemies, our perspective shifts from what we lack to who we have in Christ. Even in life's valleys, we walk through them rather than camping there, knowing that goodness and mercy pursue us. The key is not just knowing Psalm 23, but knowing the Shepherd personally and living in Christ as a new creation.
