You can stimulate creativity by changing your location. While finding a singular workspace boosts focus and primes your brain for focus work--having spaces designated for collaboration and creativity is also helpful.
Collaboration not only boosts team morale, but also sparks innovative problem solving by getting different perspectives. If you're stuck in a mental fog and are looking for ideas, try working around people. This will help you on those days.
Additionally, new locations make you more aware of your surroundings--from objects to lighting. You may come up with a creative solution to a problem at work while at a new coffee shop. Let the different people and colorful murals on the walls inspire you.
