One very popular method of breaking a creative block is simply going for a really long walk. It doesn’t necessarily need to be in a foreign country or even in a National Park. It just needs to be not in the location where you usually work. This costs almost nothing and requires us only to put one foot in front of the other for a few hours.
When you return you may very well see things afresh, as if it was a different person who was sat there struggling all those hours or days ago.
The success of this method probably lies on the walk giving you new perspective on an issue that you were too zoomed in on previously. How can we properly appraise multiple proposed methods for overcoming specific challenges without clarity and perspective?
Giving ourselves sufficient time for evaluation is also key. Important decisions deserve enough time to be considered fully. It is obviously much better to spend longer on reaching a well-thought out decision than rushing things through based on little but unintelligent impulsiveness.
So next time you face a big decision, or need some clarity, try going for a walk before continuing your analysis.
