Cover art for Three Dimensions lyrics by Something For Kate

i agree with the above comments, that's the gist of the song.

but i think it's funny that he should say that he's simultaneously "bored with" and "in love with" this mundane, limited world of which he speaks..

maybe he admits that he's bored with it, but loves it because he isn't able to spread his wings - put himself out there, risking failure, embarrassment, disappointment & breaking out of his safe routine..
