I think if you have wisdom you can have everything, even if you don’t you would at least know why you didn’t. And wisdom is the greatest thing you can have, It’s what helps you make wise choices in life. So according to Solomon, he knew that God’s wisdom was the ultimate fulfillment and it is I agree because many of us miss out on the peace that comes from God because we're too proud to acknowledge Him. But when we seek His wisdom, we find true fulfillment.
