Where Does Our Glory Come From

I'm currently reading through two books: 1 Kings and John. On top of that, I'm just about finished with Donald Miller's "Searching for God Knows What."
One of Miller's biggest things he tries to get across in his book is the idea of his "lifeboat theory." Bear with me. Roughly the entire book centers around this premise, but I'll try to condense it. Essentially, he says that the reason almost anyone does almost anything is to gain approval from others. We essentially try to receive glory from others. This is why it is emphasized so often in the beginning of the Bible that A.) Adam & Eve were naked and unashamed, and B.) why they suddenly realized they were naked and sought to clothe themselves after the fall. While in harmony with God, Adam & Eve received their glory from Him. Because of this, they were completely content with who they were. All of their approval came straight from God so much to the point that they depended on nothing else... it could be said that they were naive, I suppose. Once this fellowship with God was broken, and they were no longer receiving their approval and glory from Him, they realized they were naked. The contention was gone and they wished to receive glory from each other.
In any case, I post that summary because I'm in the 5th chapter of John and came across this verse, spoken by Jesus: "How can you believe, when you receive glory from one another and you do not seek the glory that is from the one and only God?"
It essentially restates the thing. Here on earth, in our fallen state, we attempt to get glory from one another in various ways: looks, intelligence, strength, just being "right", etc. We try to validate our own existences through other's approval. Which obviously, is a standard fallback for humanity, but not a good state for a Christian. We should attempt to to only get our approval, our glory in life from God. Is it really doable, or do we have to wait till we die to achieve that goal? I'm not sure... but I lean more towards the latter.
