Which of the following is NOT a key idea from the book of Ecclesiastes?

The idea that enjoyment comes from precise planning is not a key theme found in the book of Ecclesiastes. Ecclesiastes emphasizes the complexity and unpredictability of life, advocating for a perspective that recognizes the limitations of human striving and planning. The author, traditionally understood to be Solomon, reflects on the transient nature of human activities and the inevitability of frustrations and uncertainties.

Throughout the book, there is a recurring acknowledgment that frustrations in life are unavoidable, highlighting the futility of trying to control everything. The acceptance of life's seasons speaks to the wisdom of recognizing the ebb and flow of experiences, suggesting that one should embrace the cycles of life rather than resist them. Furthermore, the notion that life is not meant to be self-fulfilling aligns with Ecclesiastes' overarching theme of life's vanity and the ultimate futility of seeking meaning solely through personal achievement or fulfillment.

In contrast, the proposition that enjoyment stems from careful planning does not align with the message of Ecclesiastes, where enjoyment is shown as something that can be found amidst life's uncertainties, rather than as a result of meticulous control over one’s circumstances.
