I tend to subscribe to the notion that, when I attempt something new, it's not possible to be “ready” or “fully prepared.” It's been my experience that I'm much better off “jumping in” and getting my “feet wet.” Should I expect my initial performance to be flawless, however, I will likely disappoint myself. Such expectations have largely proven to be foolish. But by acting, without the expectation of perfection, I provide myself something to work with. I provide myself with a foundation to build upon and improve. Had I not started, I would still be “sitting,” “practicing,” or “planning.” But by acting, I am able to correct myself as I go.
Start where you stand. Use the tools you have at your disposal. You may surprise yourself how quickly you can learn and improve.
