My first guitar teacher, Neefa van der Schyff, used to encourage me to practice by saying that your relationship with your guitar is like your relationship with any good friend: neglect it and the relationship goes sour, treat it well and the relationship grows.
If you want to have a closer relationships, the formula is simple: time, attention and love and a big part of that time and attention is spent on mastering the various guitar techniques required to confidently perform a piece of music.
Translated into guitar speak this spells P-R-A-C-T-I-C-E.
