Go back and try try again. Giving up in defeat is more damaging than failure itself.
Here;s my true story. I was in music school. Each semester we were to put on a juried show where we played the musical pieces we'd learned over the course of the semester. As it turns out, I have/had terrible performance anxiety. I never knbew this becasue much of my previous performance experience was as a part of a group....not solo. I'd practiced so hard and was really on top of my stuff...except i was a littel shaky on this one Chopin Etude. I couldn't memorize it in time and had to play it with the sheet music.
Well, I was doing fine with my performance in fron tof several of the professors of the school and my classmates. My legs and arms were shaking so bad I could hardly play...but I was holding my own. Anyway, I had the music ofr the Chopin set up so I didn;t need a page turner. However I did not account for the fact that the AC vent was aimed right at the pia no I was using to play. Soon after I started the piece, the AC kicks in and the music starts to fall. I struggle to get it back in place and not lose a beat, but my concentration is broken. Within seconds I'm ottally lost. I can't find my place on the page and the I'm mangling the music. I wanted to crawl inside the piano and die.
I damn near gave up school at that point. However, I was pulled aside by a professor. She talked me into staying. Next semester I played the piece again and nailed it. Furthermore I learned a lot about performance preparation, reseaching hwo to deal with specific phobias, and I'm now a better musician for all that.
Lomng story but the moral is when you get knocked down...pick yourself up and get back at it. don't give up. This is equally applicable to th emartial arts or any other worthwhile pursuit.
Peace,
