Before I start writing this, let me just say, I fully realize that I am crazy.
My walls at my house are too plain. There is barely anything hanging on them. This is because I am as indecisive as a squirrel crossing the road in front of a car. And since I absolutely cannot decide, since it's obviously permanent, I just do nothing.
My walls in my classroom are too cluttered. I have stuff sticking to every single surface. It distracts me. I've seriously never had such a messy classroom. It drives me crazy, but I'm so busy doing other actual stuff that benefits the kids I never have a chance to organize. Next year is what I keep telling myself.
Why do I think about these things? See first sentence.
But seriously, my friends who struggle with distractions: would a lot of stuff in a lot of colors on classroom walls be distracting? Should I go for a more serene working environment? They're middle school, so they have P L E N T Y of energy.
