I am hoping to provide a quick answer to a short, but long winded question. In the age of the internet it seems that well playing musicians pop-up every 2 minutes, new songs get released all the time, new albums arrive daily. Why bother? Why would you bother to play, to record or to release your own music? It’s so congested out there with so many people doing “this” already.
The answer is this: What you have is special and unique. No one in the world can do exactly what it is that you do. There is only 1 of you in the sea of human life on earth. With that in mind, anything you do will be unique and special and this is “why” it’s worth doing it.
I have seen several guitar players play throught the same exact amp set-up and they all sounded different. I have heard guitar players play the same riff and they all sounded different. You can copy, but you can’t exactly reproduce another human being.
What is important to know is that you doing “it” is the most important task at hand. Likes, video forwards and the like are nice and are all a nod from people getting something out of what you did. But, that is not the point of doing anything. If you do it for doing “it” because what you have to offer is unique and can offer something to others to boot, then that is all of the reason you need.
