1) Sticky keyboards. Nothing annoys me more than a keyboard with really stiff keys--you know, when you type "biscuit" and it comes out "bsut" because half the keys are so futzy that they don't depress fully on a simple, light touch. Maybe I'm just very particular about my keyboards, because getting a new laptop has taken all kinds of adjustment for me.
2) A workspace that's too dark or too light. Squinting at the screen that's suddenly bisected by a hyper-ray of sunlight or squinting at my notes in a dark corner take me out of my zone quicker than a cat landing, claws-out, on my lap. Which happens pretty often in my house, but she's so darn cute I'm ok with it.
3) Headaches. There is nothing in this world that kills productivity quicker than the common headache. Except maybe...
4) Skipped naptimes. Two-year-olds need naps. Their writer moms need them even more.
Guess which one happened today? Sigh.
And I had so many sparkly ideas about this revision. They'll still be shiny tomorrow, I guess.
