Motivational speaker Tony Robbins in an exercise asks his audience to look around the room and count the number of brown things that they see. He then asks them to close their eyes, and recall how many red things they saw. They laugh, because they obviously didn’t see anything red, because they were only focusing on looking for brown things. I often refer to this exercise when I’m feeling negative, and only focusing on “the brown things.” 

You only see what you’re looking for. 

A few weeks ago, the weather was perpetually grey and gloomy and I was feeling quite stuck in a rut, so I challenged myself to go out and only look for colour. My attitude and mood changed almost instantly. My world became more interesting, vibrant and exciting by simply changing my focus.
