Music should be like life, it just keeps moving. No matter how many notes you missed; no matter if you completely lost your place, you keep playing. Never stop in the middle of a piece, or go back; push forward. It’s better to hit wrong notes and continue going than to stop and replay the correct notes.
With life, we don’t even have the choice to go back and do things over. So keep looking ahead and focus on moving forward it’s our only option, and the best one at that.
