He begins saying hes older than his parents when they had (what i assume) their first daughter, AKA his oldest sister. About how he's too selfish to look out for anyone but himself, and highlighting the selflessness of bringing another person into the world. Second verse contrasts the first, saying how we all die and are returned to the soil regardless of what we're buried with or who we are (were). Third verse questions who'll be there when he lays somewhere dying, wondering if it'll be just him with himself to blame for how he got there as he stares at a flawed ceiling (symbolism), or if he'll watch his legacy (children, wife, grandkids) watch him die. He wants to be buried with wealth or inheritance that he acquired from the dowry of either his future wife or future daughters. Which means that he is incredibly possessive of his women and possessions (women and possessions being the same to him, in this song at least). This is summed with the incredibly open ended stanza, saying thats the path he's heading towards unless he can rest his wandering mind and settledown and build a legacy that will precede him after his death. From montezuma to Tripoli is in an old marine corps hymn, highlighting the selfishness of marines while our nation is at war. Hopes this helps, although its a very straight forward song.
