What you should know about MTC...

I think the biggest thing to understand when coming to MTC is that there's a reason they are giving you so many incentives to join. They are asking you to do one of the hardest jobs in the world, in one of the most difficult places to do it, and to go to school part time during all of this. The first semester will be sleepless, nerve-racking, and incredibly frustrating. The second semester is mildly easier. To be brutally honest, there is a reason many of these school districts have trouble getting and retaining teachers. Nothing about this experience will be easy.
On the other hand, nothing is insurmountable. Many people before you have done it, and many people after you will, and most of us have survived as somewhat rational human beings. Once you get past the first few months, you learn to deal with the stress and how to better manage your time. The kids start to appreciate you (in very minute ways, on very sporadic occasions). You start to feel somewhat competent for at least 20 minutes a day. You have a few good moments. Of course you also have a lot of bad moments, but I've noticed that most of those moments come because we care too much in a situation where it seems like no one else does. And those are the best kinds of "bad moments" to have, at least you're fighting for something.
The biggest thing to remember is that these are teenagers who usually haven't gotten the attention or the love that they need and deserve at home. If you make that kid feel important for 5 seconds, you've had a successful day. The job is extremely rewarding, but in very small, intense moments.
You will eat, sleep, and breathe teaching for at least the first 4 months. Your roomates/spouse will know every child you teach by name, because you will feel the need to vent on a daily basis. You will go out to dinner with friends and swear that you will not discuss school, but every single topic will lead back to what happened in your room today. You will be SO sick of telling kids to tuck in their shirt, spit out their gum, walk in a line to lunch, etc... But somehow, everyday, you will get up and do your best and it will get better day after day. Every day you will think you can't do it, and every day you will...and then one day you will wake up and you won't feel like you're pretending to be a teacher anymore, you'll actually be one.
