There's a certain fast-food approach to the whole music thing that's changed the role it plays for us all. You are doing it while you are doing other things. Not that that is new - people have had music on in the background as long as there has been music.
I had spent years thinking about one thing while I was doing another. I had, in fact, prided myself on being able to do two things at once.
I am terrible at doing nothing. I'm not brilliant at doing one thing at a time, either. Ideally, I would fill out my tax return while watching a film; peel potatoes while reading the post; send emails in the bath.
I like to have a few things going on at once. It feels natural.
I can do five things at once. I'm tapping my foot, I'm opening my mouth and talking to you, and looking at the bulletin board.
Play more than one game at a time. This is a painless way to learn how to do many things at once.
I need to have many things cooking at the same time.
