Philosophy #17: Be Mindful of Form.
I hesitate to use the word “proper,” but there it is. To maximize your comfort, stamina and capacity to grow as a musician, study and emulate proper posture, proper guitar positioning, proper hand positioning, and standard fingering for notes and chords. This comes under the broad heading of following the lead of those who have been there and achieved success. The time to develop your own style is after you’ve mastered the basics.
