This may be the thing you need to know most: stop with the multitasking. It is bad. It is rubbish. Here’s someone with a psychology background agreeing with me:
One thing at a time — For many years the psychology research has shown that people can only attend to one task at a time. Let me be even more specific. The research shows that people can attend to only one cognitive task at a time. You can only be thinking about one thing at a time. You can only be conducting one mental activity at a time. So you can be talking or you can be reading. You can be reading or you can be typing. You can be listening or you can be reading. One thing at a time.
We fool ourselves — We are pretty good at switching back and forth quickly, so we THINK we are actually multi-tasking, but in reality we are not.
The one exception — The only exception that the research has uncovered is that if you are doing a physical task that you have done very very often and you are very good at, then you can do that physical task while you are doing a mental task. So if you are an adult and you have learned to walk then you can walk and talk at the same time.
That last bit about physical tasks was new to me but I think we all need reminding of the problems of multitasking. As ever, read the full piece.
