As musicians we’re all constant works-in-progress. Picture a your favorite musical moments from even the most gifted of musicians/artists alike and I guarantee you at some point one of them will admit that during one of those times, they felt they were not performing to the best of their capabilities. It’s an inevitable facet of the human existence, and a necessary hurdle to jump early on in your artistic career. Plain and simple. We cant be “on” everyday. On the flipside, there are things we CAN do to eliminate this truth from ever obstructing our creative improvement ever again.
It’s similar to the adage of “doing the best you can,” and in the unavoidable events where things still go awry, it means cultivating a resilience that comes from being experienced enough that your “mistakes” are good ones- or not noticeably mistakes at all.
