How have you changed since september?

Since September I don't see a big change in myself. There is definitely no change in my personality, but I guess I have made some minor ones. I've noticed that in September, I guess I was still in the ''summer mode'' so I wasn't giving all that much effort in school but I quickly changed that when I came to the realization that it's my last year and that it's time to smarten up. Another change I have noticed is that I'm much more organized than I was in September, even October. Other then these few changes, I don't think I've changed anymore.
