The answer would be self-reliance.
From the start of the poem the speaker iproposes us to the sudden realization that we can listen to our own self-conscious and still excel through life.
This is found through the lines:One day you finally knew
what you had to do, and began,
though the voices around you
kept shouting
their bad advice –
though the whole house
began to tremble
and you felt the old tug
at your ankles.
In this case, the speaker of the poem leaves us with the task to find our own voice, in a world where society as if to speak for everyone..
