When you do a lot of concentrated work (if you are privileged to be in an environment where this is possible), it is good to do something completely different at times. I discovered that when I switch my mindset to someting else more relaxing like leafing through impesssing images, some of the previously unanswered questions get solved automatically in my brain and what is more – it has a relaxing effect on me too.
This phenomenon led me to discover ‘Photoblogs’. Here is a source: http://www.coolphotoblogs.com
