@ Pastor, like everyone else above says, you are on the wrong path.

One, you may put too much pressure on the students.. Secondly, you may set their goals too low. What if their parents are drug dealers or chang'aa brewers? Haalllooo! We all want to be better than that.
I agree with @Guka, decline the invite... Or get a more inspiring message. Look into the bible, you will get lots you can use.
....above all, to stand.
