9. Get ready every morning
Why bother wearing anything more than sweatpants, right? Wrong. Getting in the habit of waking up just before you need to sign in for the day is no good. You should start every morning as if you were headed off to the office, showered, shaved, and dressed. Not only because you're a civilized human adult, but because it will also help put you in the frame of mind that you're actually headed to work and not simply settling in for a day of lounging around the house.
10. Keep your desk clean and presentable
There may not be anyone around to see your wreck of a workstation, but who knows when the boss may announce an impromptu video conference call. You don't want to be caught shirtless covered in crumbs and clutter.
