i think you can practice at home, but eventually you have to apply yourself to performing. the first time i played in public in a virtually empty club - my knees were knocking, and my picking fingers turned to jelly.

i was lucky - the people who ran the club were very friendly and encouraging, and you owe such people a great debt. i have always tried to help and encourage others even if their style wasn't my cup of tea.

the guy running that club has been one of my best friends for nearly forty years now. being dismissive and snotty about other peoples' tastes doesn't prove your expertise.
