I have a hard time with marketing too as it seems the most hustle oriented and requires constant vigilance. My motivation dwindles much past the website/product design but everyone likes the product. My project is stupid simple and has a niche customer base. I don't know but I'm thinking it might be best to hire a marketing person on fiverr or upwork and have them manage marketing. I don't know if the return would be worth it though. Have you looked into hiring someone to do the social/marketing work?
