Three things invariably happen when I work out-of-the-office from Panera (which I do most Fridays)...

1. I drink WAY too much coffee
2. I wind up freezing - I guess they think if you're cold enough you'll want to buy coffee?
3. I get a lot of work done

I'm not sure what there is about working from my office at LifeWay - it's relatively quiet enough. I still wind up getting less done on a typical in-office day than I do on an out-of-office day for some reason.
