How do you get better?

Do you launch at stuff or just bey with other people?
My bro was launching his bey at chestnuts until he got really good and could start to break them with 1 launch.
(these chestnuts big!)
Use good combos and get better launching strength. But like aforementioned by Wyrm, this is pointless.
Anyway, at most just ask in the "Ask a question, get an answer!" topic.
