One of the best pieces of advice I can offer any student is to plan your practice. Time is precious and you need to make every minute count. Start with short practice sessions of 15 to 20 minutes and break it down into 5 minute topics. Example; 5 minutes picking practice. Leave your left hand out of it (right if you are a lefty). 5 minutes chord practice. Left hand only. 5 minutes Scale. Start slow with a metronome and stick to one scale. Even one string. 5 minutes song. Work on a small section of a song. Just a few bars. Make sure your practice is leading you towards your ultimate goal. Try writing out practice plans when you are sitting on the bus or train or in the waiting room at your guitar school.
