My tips for new teachers are going to simple (I'm still working on them myself).
1. Be creative....
Don't be afraid to create fun and exciting projects that go beyond the textbook. The students will love it!
2. Be flexible...
I have been teaching for eight years now, and I have moved grade levels and classrooms multiple times. Each transition has taught me something new, and helped me prepare for the new grade level.
Also being flexible means, don't stress out when you don't get through all your lesson plans like planned.
3. Ask for help when needed from your principal or other teachers.
4. Go to workshops to get great new ideas!!!
