Dude this is al a lot of crap.
You call yourself a drummer?
I mean, I drum for one of the world’s biggest brands ever, and even i use sheet music sometimes. And if you like to do everything by hearing that's your idea of drumming, and it's not necessarily better... And as about being better when you do it by hearing WRONG you can't be good if you try to do everything on your one, read some sheet and practice it's harder than you think, and in the end you will have a lot of help from it.
