One of the reasons I’m so pharisaical about my phone, email, and social media is because I’ve come to realize the obvious: multitasking is a myth. Literally. Only God is omnipresent. I inhabit a body. A body that can do only one … thing … at … a … time. Multitasking is just sleight of hand for switching back and forth between a lot of different tasks so I can do them all poorly instead of doing one well.
