Teaching is a very good field... just remember a few points.
-Your first year of teaching will probably be hard, due to the fact
that you have to get a good flow of your lessons and your
teaching style. Don't be surprised if you're the first one to work
and the one of the last ones to leave; it's not always 9-5.
-You will have to learn how to interact with parents(even the
crazy ones)

I've had parents want to call me at my
house.WTH. It's all about balance... after a certain point you'll
be able to discern the ones who aren't "wrapped tight".
***Behavior Management***
This is the area where you've really got to be consistent -kids will try you- and if you don't nip misbehavior in the bud, your whole classroom will be in disarray. Be strict first, then if you have a good set of students, lighten up and give them more freedom.
-Say what you mean and mean what you say. Ex: If you have a due date for an assignment in your class -let it be that. I've gotten excuses from I fell asleep; to a parent telling me that they couldn't buy their child any paper because they spent too much money on Cannabis. Yet their child is the main one trunked down in SEAN JOHN and Air Force Ones. Oh please you can keep that!!!
***Finally***
Have your own life outside of the classroom -when you do other things besides teach, you're not as frustrated once you get to work.
