Your brain is a very busy place. It would be at least twice as productive if you let it take care of all the work it is racking up on a daily basis. Unfortunately, your brain is so busy it can't always focus on everything at once. Sometimes big, complicated thoughts have to be backed up, so your brain can find time to think about something new. The trick is to find the new thing that your brain spends most of its time on.
