I noticed something phenomenal in my schooling life as a debate-geek... The older the debater, the worse they were at adapting. What fascinated me was that as I aged to around 17 hitting my last year of school, I noticed something phenomenal; I got better and better but others got worse and worse as they got older.
There is something they lose in creativity that is horrifying to me and it's most blatant in the 15-16 period for most males. They suddenly become so rigid in their style and thinking and become TERRIBLE last-round carries for the team. I never got to properly lead a team because by the time I was 17-18 I moved schools, it's a long story. So basically I had zero rep-worth in my new school and lost my credibility as a last-round monster. I would come up with insanely creative comebacks that judges said they'd never ever heard before on the topic in 12 years of judging and stuff.
That being said, I was a very irritating individual due to emotional shit I was going through and my teams often hated how bad I was at team-playing and I regret it but regrets make you improve as a human being so whatever I improved due to it. I was stubborn and horrible at working around the thinking-patterns my teammates had on the topic. Instead of going with their flawed strategy and making it as great as it can be, I would always want to force the optimal strategy onto them and in hindsight I knew so little about people back then it was scarily pathetic.
Anyways, I don't regret it; debating teaches you so much about people but as a life skill it's nothing but a pointless hobby outside of your own brain because people hate debating and adore people who make them feel smart and correct.
