A performer tells their story through their song or act, but to get people to listen [just like you], they have to market their product. They have to tell their story beyond the bounds of the art they have created. They have to get skin in the game, put themselves out there and be relentless in what works!
Where will your marketing efforts be when Facebook isn't "it" anymore? Will you move to another platform, will you be established in another form of digital marketing and ready to roll? If you are smart, you will prepare your business by using and testing other forms of online/social marketing - Instagram, email, LinkedIn, Twitter, etc.
