Oh no, he gave up debate? That's one of the most useful activities in life! I can't believe I missed this thread the first time.
I don't know, I did the same thing in high school, and I just <I>made</I> time for it all. A lot of my friends were quitting things for that same reason, and there was a lot of parental thrust behind it too. When it involves a team, it puts a lot of pressure on the other members when someone quits. I don't know... it's not my philosophy, for sure. I think a person needs to make time to follow through on their commitments. I did debate, a sport year-round, a competitive book club, a competitive problem-solving team (tackled the newest social issues), tutored young kids in reading, led a peer mediation group for teens on probation, and did 30 hours community service/semester for the honors program. There were a lot of things I wanted to quit, but couldn't do so without sabotaging the team or the program. You just learn to make it work. Sleep can suffer. Hobbies suffer. I quit playing piano, which was kind of a bummer. But I don't know... I don't regret it. And if I did have to quit something, it sure wouldn't have been debate. That gives you research skills, public speaking skills, writing, planning and perspective... it was one of the most useful things I ever did. Big time commitment though. Everything worthwhile is, I suppose.
ETA: Actually my parents did make me quit one thing. They made me quit a foreign language class because they thought it would be confusing to learn two languages at once. I still regret not learning Spanish. That would have been more useful than Yearbook, which is what I had to switch to in order to quit Spanish...
