I need some inspiration

I'm in the process of setting up my classroom, and I need some help. Last year I made this cute poster that said, "Alone we can do so little, together we can do so much." -- Helen Keller. I cut it into pieces and we put it together. I had the students all sign it then I laminated it. It hung in my classroom the whole rest of the year. When I took it down I was sad, and I knew I had to do it again. So, I am looking for a new quote for this year. Either about teamwork, knowledge, or anything else inspirational. I don't have a strong theme in my classroom, so anything will work. If you have any ideas post a comment and let me know. I would love to have something great to start the year off with.
