Seeing other musicians better than you, is a great plus. why? bec. you'll be inspired to practice more, work harder, adding extra hours on those scales,finger dexterity excersises, so on so forth. In my experience, any musician that I've met who said that they are already good, was stuck as to were they are,no more improvements, magaling na daw sila,hangang doon nalang sila. I always say to my self "maraming pa akong bigas na kakainin" and true enough nalampasan ko na iyng mga nagyayabang sa akin, hehehe Utube is a great insperation
