On Debates and Five Minute Feuds

I love debates. They are exciting, thought-provoking and they satisfy my need to argue and prove others wrong (Yes, I know it's kind of childish, but I don't believe that you've never felt that urge.) However, this is something that I wouldn't imagine myself actually enjoying five years ago. Back then,  I was a poor public speaker. Delivering a speech in front of a small group made me stutter and shake so badly that I felt this was one of the worst forms of torture ever. Now, years of practice has given me confidence, and a feeling of enjoyment whenever I participate in a debate. Unfortunately, success in debate does not translate into victory in arguments. I still lose almost every argument I have with my little sister.
We've been doing Five Minute Feuds in British Literature, a short form of debate where there are two teams of three and everyone has 50 seconds to argue their case. You need to be short and concise when stating your arguments, because there is little time. This was something I kept forgetting. In a normal debate, you have four or five minutes to state your case, which gives you the opportunity to state your arguments, counter your opponents and expand on your points. A Five Minute Feud doesn't give you time to do that. What it does teach you is how to keep your arguments short, to the point and powerful.
I don't think I've mastered the skill of being concise and to the point yet, so I think I will stick with longer debates for now.
