Though everyone will tell you it's multi tasking and time management --I too am struggling with this myself. I work for my husband full time, run Etsy shops part time, am on 4 teams, (captain of one) and write and travel constantly. Truth be told, there's not enough Etsy time--and of course, since we love Etsy most we want to find time to maximize our Etsy time!
I have decided to make small adjustments in my day:
SAVE TIME PROMOTING: Try to set up networked blogs, or an application that if you post to a blog, it will auto-post to facebook. In turn find out how to link in Twitter to one of these.
I start with a blog post, then post to my Tweetdeck, which posts to my facebook and tweets it to everyone. I use TweetDeck thanks to texasvintage.etsy.com who taught me how to use it. I can launch this (free service) and post one update to multiple twitter accounts and several facebook accounts including standalone pages. This has been a huge timesaver.
QUALITY TIME:
It's better for me to hit Etsy hard for an hour in silence than 3 with the tv on.
RELIST:
If you can't list new items, relist some old ones but change the tags and update keywords and titles for maximum exposure. Looking at something now rather than 4 months ago may give you new ideas or keywords. This will also gain you exposure by relisting if using team tags you will be on the first few pages in and hopefully nabbed for a treasury.
I will write more about this later.*see i'm time managing myself* Hope some of these may help.
