MUSICIANS!!! what is your worst fear in "making it" as a musician?

The first time I ever performed live was when I was around 11-12 and I played Soul Sacrifice by: Santana on the kongas at the Trocadero. Before that I played at the Downingtown School of Rock but it wasn't in front of many people. I count the Troc as my first live performance because it was in front of a lot of people and I mean around maybe 300 and up.
