Multi-tasking Will Kill You
When I’m playing chess while talking on the phone, not only am I barely able to focus on the phone conversation but my chess rank goes down by about three standard deviations. In other words, the non-phone version of me can beat the phone version of me 95% of the time. That’s a big jump down. And this is a result of doing just two tasks that I’ve done for tens of thousands of hours since I was a kid.
What do you prefer, to complete 10 tasks at only 5% of your potential, or chose the most important one and knock it out the park?
