One of my favorite scenes in the movie, Dead Poets' Society, is when Professor Keating has the students stand on his desk and face the classroom, so that they can see things from a different perspective.
When things seem to stagnate in our lives or in our learning, it's time for a new perspective. Relax. Have your children prepare dinner. Take a walk. Sing in the shower. Dance in your front yard. Make a hat with items you find around the house (and wear it!) Read a Shel Silverstein poem. Make faces in the mirror. Blow bubbles.
Now, what was that problem, you were trying to solve? Oh, yes. Ideas are flowing now!
