You will hear now and again people bragging about their multitasking abilities. However, it’s only bragging. Jumping from a project onto the email inbox, and then onward to Linkedin, breaking news that popped out on your smartphone, checking out the meme you got in a casual Slack channel, or a Medium article that just arrived in another, is rarely a great idea when you have a task and a deadline.
Refocusing on your initial task takes around 15 minutes, though some say it goes to a whopping 23 minutes and 15 seconds, so the math is clear. In the best-case scenario, if you get distracted only 3 times a day while you are at work, you are losing one whole hour of effective work.
Of course, the numbers in different case studies may vary, yet the fact of inevitable task-switching cost remains.
