MVL of the Trip?

What were some of  the most valuable lessons that you learned while on our recent trip to STN?  Was it something you learned in a breakout session?  What is something you learned while competing?  Was it something you learned while having to live with other people for two weeks away from your parents?  Did you learn something about yourself in the process?  I'm interested to find out what were some of the most important lessons you learned while on our trip.  

If you were a student who stayed back, I'd like you to tell me about some of the most important lessons you've learned this year while being in the class.
