I busked playing sitar in the summer of '93 on a playground-of-the-rich resort town. I had a day job and busked in the evening. It required a police permit, which was free, and I was assigned a spot. It happened to be a lonely street corner across from an upscale al fresco restaurant. One night, an Indian gent & his missus came over as they were leaving the restaurant. He told me how wonderful it was for him to hear Indian music played properly, and put a $20 in my case. That was a wonderfully affirming moment.
There's nothing like an appreciative audience to bring you out of your shell.
