It's not easy what musicians go through. Though some people think the word "playing" has a sense of slacking off, musicians view the word playing as "work". It takes an incredible amount of work to even be competitive in a world (especially in DFW)saturated with very good performers. While some may think being a musician is easy, I can tell you from personal experience that it takes years of practice to simply get an opportunity. The moment you are given that opportunity, it's important to deliver so that people ask you back. This is why it's important to develop consistency in everything you do, so that you can be ready when you are called upon.
