I used to be a chronic multi-tasker.
“Used to be” is probably being a little too generous.
I still find myself, throughout the day, attempting or at least thinking about more than one thing at a time. Sometimes, I begin to feel it both mentally and physically – a sense of unsettledness, like I am scattered.
At these moments, I can (now) take a breath, slow down, and remind myself to focus on the one thing – the one thing that I need to do right then.
Dan Harris of 10% Happier says Multitasking is code for doing several things poorly. When I remember to focus all of my effort on the one thing I am doing right then, I am more efficient, and more productive.
But, mostly importantly, I am more at peace.
