Multitasking is counterproductive
 

We’ll repeat that, in case you were focused elsewhere! Doing homework with one eye on group chat and the other on your favorite YouTube channel is unlikely to add up to success—or enjoyment. In fact, what you’re really doing is ”switch tasking,” bouncing from one thing to another and back. The next time you find yourself doing so, pause and notice. Then set yourself a time limit—start small—to see if you can focus on one thing at one time. Notice if and how your experience changes.
