Too much, especially first thing in the morning. I've been up for 2.5 hours, and while I have watered the garden & fixed breakfast, the rest of my time has been spent bouncing between etsy, Facebook, and Pinterest. Oops!
But now I am off to work, and will stay away for a few hours since there is nothing left to hold my attention :)
Moral of the story: If you feel like you're starting to waste time, you probably are.
