When I'm struggling to be creative and motivated at work, I turn to side projects and hobbies. Seems crazy to fill an already busy life with things like photography, board games, or distance running. I think that's exactly the thing we need to clear our minds and jumpstart creativity.
Kevan Lee at Fast Company:
San Francisco State psychology professor Dr. Kevin Eschleman and his colleagues measured the effect of creative hobbies on over 400 employees. In two separate groups--one rated by coworkers and one self-rated--those with a creative hobby were more likely to be helpful, collaborative, and creative with their job performance.
As an added bonus, outside of work those with hobbies felt more relaxed and in control.
