I keep my shop mainly as a hobby, so I give it the free time I have, but I don't lose sleep over it.
I only post 10 listings at month (tops). If I sell, it's fine. If not, it's fine too, because I do it as a hobby. Besides, my articles are not "everyday use" for most of the people. Check my shop to see what I mean:

They say it takes the right person at the right time to make a sale. The best advice I have been given is promote, promote and then keep promoting.
Other than that, internet shopping offer is SO big, we can only keep trying.

I know how you feel, I've been there...and it's a frustrating hair pulling feeling :D It normally happens right when your starting out, and getting everything set up.

Normally I make 1 item per night sometimes 2, I take the photos of them and write up the listing, theres an easy way to save a listing for later, convo me on Etsy if you'd like to know it. After I get off of work I come home, post the new item. I spread out my listings (2-3) to one ever hour ie: post new item at 4pm, renew an item at 5pm, renew another item at 6pm. I spend or try to spend about 30min on marketing, normally between the listing times. Then make dinner, tend to family, then at 9pm I make another item. *phew* I'm tired just reading that!!

It does get easier, you'll find what works for you and soon it will start to flow. I don't know if this was much help to you, it's just the way I do it.
