Does your glass tend to be half full or half empty? If you ask your colleagues, they'll say it's half empty. Wrongfully so. That's not you. But that's how you appear to be. Do something about it! Stop drinking your espresso from a standard cup. Use the Coolblue Espresso Mug. It's the perfect mug for your shot of caffeine. It'll restore the balance between cup and coffee. In your favor.
