You can have wealth, material things, and go many places, but to have peace, you need the Lord.
Read: Deuteronomy 8:3
“Yes, he humbled you by letting you go hungry and then feeding you with manna, a food previously unknown to you and your ancestors. He did it to teach you that people do not live by bread alone; rather, we live by every word that comes from the mouth of the Lord.”
