Not surroundings, abilities --

Not our house or bloodline.

...

Each of us, in the sand, draws a line,

Chooses path of right or path of ease:

It is our choices that define.

...

We are, all of us, given life, time,

What we do with it molds what we will be,

Not our house or bloodline.

...

Your life may taste of the bitterest brine,

Or you may descend from an old family;

It is our choices that define.

...

The Sorting Hat's choice is not a sign,

We are responsible for actions, beliefs,

Not our house or bloodline.

...

Fate is not written in stars aligned,

We choose what do to and we choose what to be.

It is our choices that define,

Not our house or bloodline.
