" To earn money from busking, I believe that you must believe that you have every right to be there and you are benefitting your audience as much as they are benefitting you. If you cannot perform with dignity, the only money you will get will be from those people who feel sorry for you. Your heart will not be in it. Inevitably your performance will flag, and you'll stop because you don't think it is worth it.
However, if you perform well, people will connect with your performance and they will want to reward you for the music."
