Everyone has their own goals of what to do with their business.
Me, personally, I want mine to go full time. It's what I have wanted to do for a long time. I ran the numbers to see what I would have to do in order to make this full time successfully (ie, cover my bills, cover the business bills). They're not accurate, however, as I have not made my calculations factor in things such as etsy fees, taxes, etc. But It's given me a decent idea of where to start. All I have to say is...I have a ways to go before this can go full time for me successfully.
Are you trying to make yours full time or are you wanting to keep it to part time? Have you ran the numbers to see what you have to do in order to make your goals happen?
