When i was a beginner and maybe up to now..
"Practice makes perfect" and the most important one "Everybody has a start.. So if you just started and you see people doing nasty and crazy fills, grooves.. they started as singles at 60 bpm"
got it from spikeydrummer
i'd like to tweak this a lil bit, "Perfect practice makes perfect". Panu kung pinapractice mo eh mali?
"Practice makes you consistent" i believe should be apt.
Another mantra that any drummer (which includes me) should live by, "Always be on time, rhythmically and personally as well".
