Thirsty?.....But for What?

I'm looking forward to seeing you all on Sunday at worship. Speaking of worship, I've been thinking about what true worship is and what competes with it in our lives. Revelation 21:1-8 has been where I'm reading and there worship is defined as "thirsting for God". Question:  How do I find my deepest satisfaction in God? Question 2: What do I thirst for that competes with my thirst for God?  The answer to this, I believe, are the idols I have set up against/in place of God.  What do you think?
