As a busker, one thing that does not work is self-consciousness. A busker needs to be working. A busker needs to shed all ego and get down to work. Play your songs, play them well, earn your money, and don't get in people's way.
“God has stated in clear and concise language how He created the universe and we ought not to doubt His Word.”
“Love feels no burden, thinks nothing of trouble, attempts what is above its strength, pleads no excuse of impossibility; for it thinks all things lawful for itself, and all things possible.”
