A number of people I know claim to be great multi-taskers. The brain, however, doesn’t work that way; instead it focuses on one activity at a time. If you switch back and forth between multiple tasks, your brain works more slowly than it would if you focused on each activity for a period of time. Albert Einstein said: It's not that I'm so smart, it's just that I stay with problems longer. Most of us do the opposite -- with predictable results.
