Theme for Dead Poet's Society

I think the central theme for Dead Poet's Society is Carpe Diem. It was spoken throughout the whole movie and each character went by that saying whenever they wanted to do their own thing. I believe by seizing the day they were able to do conquer things that they would've never thought was possible. Each of them had a fear of something such as their parents or girls or getting in trouble, but once they understood the real meaning of Carpe Diem they realized they only have one life to live and that they need to take any opportunity that came to them. Even when they remade the secret society club in the cave they were living their life with a risk. They knew that if they get caught they could get in trouble but the whole point of it was to go out and do things that seem fun but also risky. They were all able to learn that things don't just come to you, you have to have to courage to go out and get it yourself otherwise you wont get anywhere in life.
