One of the most awesome truisms I ever found is: you REALLY don’t understand something unless you can teach it to someone else and they ‘get it’. It’s cliche for a good reason – it’s really true. A little related thing that never ceases to amaze me: No matter how many ways we try, we can never see the 8th corner of a solid box. Lacking multiple perspectives, we have to imagine the 8th corner. Even babies deal with these kinds of mysteries in their own fashion – imagining the unseen.
