Just found this great post:
Doing everyday things in unconventional ways can stimulate creative thinking. This study had people mix up their usual breakfast making routines. That alone resulted in higher scores on creativity tests.
Via Miller McCune:
Want to boost your creativity? Tomorrow morning, pour some milk into an empty bowl, and then add the cereal.
That may sound, well, flaky. But according to a newly published study, preparing a common meal in reverse order may stimulate innovative thinking.
