I agree with previous posts, it's a 4 year challenge sometimes. I've seen it and have been a part of it in the past. The hardest thing to do is to come in Year 1 and let a LOT of things slide. But, as you're going through it, you take notes of how you can make things happen your way, but the kids feel like it's really THEIR way.
Some fights aren't worth it. You do have to be prepared to do some things differently, every community has different expectations, and what worked at your old job may not be the way that will work at your new job. There are a few things that I would NOT let slide at my previous job that are now a part of my program because, honestly, they're right...it would be a huge mistake to try to change something that has positive results even though I don't do it that way.
Best advice to you is to get to know the kids one on one as much as possible. Let them know about you, reach them on a personal level, and if you're making changes to things they love, have a better reason than "I don't like doing that" For example, I had to make my seniors read the laws on hazing and let them come up with the idea that they had been doing things wrong...not me.
