Lyric discussion by FFAMikey 

I think a lot of it is about becoming more complicated as you grow older. As a child, you're not so emotionally complex and everybody smiles, you feel known and accepted, but then as you get older, you might still be happy, but you become a much more complicated person and nobody REALLY knows you anymore.

I think there is this aspect to the song where one includes themselves in not knowing who they are. There are so many layers and sides and complexities of a human personality that even you are on a journey to discover who you are. If you like yourself, who you've become after everything life throws at you, then that process of discovery is enjoyable.. which sort of relates to the "happy as a clam" tone of this song. Its also separate from narcissm, where you just can't get over youself and this feeling is no way is related to that....
