Recharge Your Stylus-
I found this out recently, and it turns out that it really helps out a lot.
If your stylus is low on power, take it to the Ranger Center and talk to the lady behind the counter.
She will ask if you want to recharge your stylus, and click yes and Presto! Finished. (For beginners).
