I'm fortunate enough to have an office overlooking a small pond. When I'm frustrated I go to my window and stare at the pond for a while. When I'm really frustrated I walk down to the pond and stare at it for a while.
I also walk to lunch as often as I can (i.e. when it's not freezing or boiling outside). Highly recommend.
Walks have helped me a lot in all aspects of life while dealing with problematic situations (as a refugee in Belgium). For the last couple of years, I have devoted my free time to a creative project called awalkaday.art.
