If you had last year to live over again, what would you change?

this is the topic for the last unit in my class... isn't a weird idea of mine =P ...well, i don't have a really interesting answer for this question, because i don' t change too much things from my past... because normally, i try to don't take the thing sooo seriously... but i know my teacher wants to discover dirty secrets jaja and i will try to put something more intense in the homework....
