Multitasking is out. 
Turns out this badge of honor from the ’90s is more fiction than fact. Our brains don’t multitask, they just rapidly switch between tasks, sometimes fast enough for us to believe we’re doing many things at once. Problem is, every time we switch, there is a “ramping cost” in your brain, it takes anywhere from a few second to 15 minutes for your brain to fully re-engage. This makes you feel insanely busy, but simultaneously craters productivity, creativity and increases feelings of anxiety and stress. 
Multitasking also requires you to hold a lot of information in your working memory, which is controlled by a part of the brain known as the prefrontal cortex (PFC). But the PFC is also responsible for will-power, and for keeping fear and anxiety in check. Multitasking increases the “cognitive load” on the PFC, overwhelming it and effectively killing it’s ability to keep fear, anxiety and the taunt of distraction at bay. 
Simple solution–just say no. Do one thing at a time in intense, short bursts.
