Sales are slow for me, too...but I refuse to give up hope. I'm hundreds of dollars in the hole on my business alone. I have 2 kids, a mortgage, bills, etc. Thankfully, I also have a very supportive partner by my side. I spend endless hours not only making my items, but also promoting on different websites and social networks. Every time someone favorites an item, let alone buys one, I am flattered. The reality is that it's a job, not just a hobby. This is a dream, not a get-rich-quick scheme. No one should ever give up on their dreams.
Good luck and keep hope!
