I believe in the "do what you love" philosophy,(but) it works for some and others it does'nt. Music is different from other professions in that it is also a show business. Musicians tend to be introverted(even some drummers..lol)so performing on a regular basis can be really stressful. That said, there are some that thrive on it! But even those guys dont always "make it." As mentioned, being in the right place/right time can be equally important. Luck. I've been playing many years but could never convince myself i was good enuff to go professional..maybe i'm just lazy..lol..but it is alotta work. I've had several bands and have done the occasional gig..and some even paid..haha guess i dont have any advice that you have'nt already been given. Just know that you are not alone and keep jammin when you can.
