Something I Wish I could change if I could go back in time

The one thing i would change if i go back in time will be my middle school years. The reason i would want to change my middle school year is because i had really messed up. I was never focused and was't willing to lurn. My middle school that i went to was called jonas bronk Academy which is in New York . It was a very small school so most of the time kids just go in when ever they feel like. I used to do the same but now i really regreat it and wish i could of change that in time.
