i think that this song is talking about being your self. The line "your only as small as the world would make you seem" is talking about the fact that if you let what ppl say affect you, you wont be able to be happy hence the line "I'll say hi but not reply to the letters that you write because i found some peace of mind" is saying that he will finally be himself and not care what ppl will say about him.
But thats what i think but yet again what do i know
