history: I won the national debate championship.  The results came in and I won the national debate championship with my team! Hey_comma_ congratulations. That must have been a lot of hard work. I wish I put more time into extracurricular stuff like that. It's a good look in the future. Especially the debate team--you develop so many good life skills with that!
current: I agree, it was a proud moment for us! I had to sacrifice a lot of time and energy to be able to get here. 
next: I bet... that's a lot of weekends and late evenings practicing and honing your skills. I'm sure it's a lot of positive intangibles developed that you will reap the awards from later on in life.
