A little romantic chemistry never hurt anyone. Sure, it may not be entirely appropriate, but you can’t help what develops naturally between you and certain coworkers. Keep everything on the up-and-up, but let the magic between you and you-know-who fuel good things at work. You are, at the end of the day, a professional, and you’re getting better and better at translating your social prowess into productivity. Mainly because you’re so intelligent. But also because you have the capacity to be calculating. At the end of the week, hang up your hat and have as much fun as possible.
