Can you identify this photo?  Sometimes just changing your perspective can spark a new idea.  This means looking at familiar things in a fresh way - or from a different angle.  Travel is a fantastic way to shake up your brain by immersing yourself in new experiences...eating local foods, speaking with strangers, admiring a different landscape.  Even if travel is a regular (and exhausting) part of your job description, use it as an opportunity to look at business challenges from a new perspective.  That's what I did on a recent stop in San Francisco (big photo hint).  Do you feel invigorated after a few days in a different location?
