You don't know destiny if... You've never said "Who's got the chalice. I need the chalice. I'm flashing red" You've never had flaming blue hair, or gotten kicked to orbit on a team wipe. You've never selected the hardest difficulty on the weekly heroic because you need those 9 strange coins. You didn't make nightfalls the first thing that you did on reset day because of the buff. You haven't gone back to the tower to turn in bounties and put gear in the vault for the next character to pick up.
