Some of you might not have those advantages. Maybe you
don't have adults in your life who give you the support that
you need. Maybe someone in your family has lost their job
and there's not enough money to go around. Maybe you
live in a neighborhood where you don't feel safe, or have
friends who are pressuring you to do things you know
aren't right
But at the end of the day, the circumstances of your life -
what you look like, where you come from, how much
money you have, what you've got going on at home - none
of that is an excuse for neglecting your homework or
having a bad attitude in school. That's no excuse for
talking back to your teacher, or cutting class, or dropping
out of school. There is no excuse for not trying.
