What is the meaning of ''until the shine wears off''?

I love the songs Lost! and Lost? (well, it's the same song but in different versions) by Coldplay. In these songs, we can hear:

I just got lost

Every river that I tried to cross

Every door I ever tried was locked

O-oh

and I'm just waiting 'til the shine wears off

What does until the shine wears off mean?
