What would you like a new teacher to know?

As I’ve mentioned over and over and over on Fluther, I’m getting an elementary teaching license. I should be student teaching in the fall and hopefully getting my own class soon after.

I think my classes are doing a good job preparing me, but I’m wondering…
Teachers- What advice would you give to a new teacher? What do you wish you knew getting into the profession?
Parents/caregivers- What’s your experience been with new teachers? What’s gotten you really excited about a new teacher, and what’s happened that’s totally turned you off?
Students: Do you remember ever having a first year teacher? What was awesome and what sucked?

I want to be good at this. :)
