Eavesdropper:

My contract will expire when I do.

Nobody will reach all the children. But that sure as hell doesn't excuse anybody from trying. If you want to cop out and say "can't teach to street wise thugs" that's YOUR business. Damnded If I do.
I plan on getting paid for my work, and I'll earn every red cent. I may not save them all but If I can raise one young life from failure it'll be worth every cent I sink into my education. All the filthy money in this world is bupkis to a living mind, that has the potential to do anything.

P. S.   I don't claim to know any secrets about teaching. There is no secret as far as I am concerned. For every lost child on this planet there is someone, somewhere, that can reach them. I will be that person or will find that person for as many of my students as God wills.

Signing off with my real name, because I have said things I will back,

Chaz
