ok i have always wondered why i cant seem to do the vibrato like how everyone else does...i realise everyone moves the whole wrist when they do it...i just use my fingers to pull and push the strings up and down...no wrist action at all...is it okay if i stick to it? or will it affect my playing?

oh yeah and i find it hard to do the way most people do it....for some reason...i cant do it as fast...i cant believe that i have been doing a weird vibratos for the past 8 months or so...
