Nothing kills productivity and creative quality more than a lack of focus. You don’t want your surgeon thinking about what to make for dinner when he’s supposed to be paying attention to what he’s cutting.
You also don’t want to be thinking about dinner – or email, or taxes, or your next meeting – when you’re supposed to be focused on what you’re doing right now.
Practicing mindfulness and meditation enable focus.
Put the badge of multitasking aside and spend a week trying to be fully present in what you’re doing in every moment. How does your efficiency change? What changes in the quality of work do you see?
