Just keep in mind that if you’re even holding an instrument in front of others, you’ve gone farther than 99% of them. That goes double for banjo. People just enjoy live music. Even if someone in the audience happens to play better than you, chances are they’re still enjoying your playing.
When I started a band back in 2011, I was terrified to play in front of people, but I knew that’s exactly why I had to do it. It took less than a year for me to get over the stage fright… and I made some memories I’ll never forget.
For me, stepping out of my comfort zone has almost always yielded fantastic results.
