Why is pursuing happiness outside of God a mistake?

Pursuing happiness outside of God is a fundamental mistake as it focuses on temporary pleasures that fail to fulfill our deepest needs. The preacher warns against the delusions of seeking happiness in fame, wealth, education, and pleasure, stating these can never satisfy the soul's longing for true joy. Instead, these pursuits often result in a 'great empty place' in one's heart, which only God can fill. History and personal narratives attest to the futility of finding lasting happiness in worldly pursuits, reinforcing that without God, our happiness remains superficial and fleeting.
