While you’re out there gathering information from experts, it is imperative to remember that the times-they are a changing. In a Facebook group that I am a part of, a fellow musician was talking about the hardships of selling recorded music as a form of income. Record sales are a perfect example of this shift; just because something worked 20, 10, or even 5 years ago does not mean it will work now, or when you are “ready”. Looking back on the entire history of music as a profession, record sales as a major income stream will be a blip in the tale.
Zoom out far enough to see the blips, have footing in what works now, and be flexible to change for what’s to come. Sitting back and remembering how things used to be is time spent; someone else is out there making “the now” work in their favor.
