Question

What do you wish you had learned in school that you didn't?

Answer 1

so far...

study habits.  

Answer 2

i wish i learned how to solve disagreements better. it seems to me that there are a lot of mean people in this world. maybe if we learned how to settle our differences peacefully at a young age, there wouldn't be so much violence in the world.  

Answer 3

Everything. I was too lazy and easily distracted in school. I'm retaking it all though.

But REALLY, i wish i'd learnt...  cheerleading, or ice hockey. Neither of which are really taught in my country.

Also - a language or two.
