Watch the Take Your Time online guitar lesson by Cathy Fink from Clawhammer Banjo: Beginner Module 1
The beginning exercises will mold what your playing will sound like. Take your time and make sure that you are able to do each exercise well before moving on to the next one.
There's a temptation to play fast, or to be in a hurry to get to the next lesson. Let go of that and get into the zen of systematic practice. You'll enjoy your own playing more when that practice pays off and you're making great music.
