Whats an example of flexible thinking?

Flexible thinking is unbiased thinking; Thinking outside the box, an unconventional thinking. For example:slicing the pizza into equal 11 pieces: Place the slicer touching the rim of the pizza and move it around the pizza repeating the word PIZZA out aloud at equal intervals.Keep doing this for a while until you reach a comfortable speed of uttering, for a count of 11. Now that you have established the rate of uttering the word for a suitable count, simply cut along the points when you finish saying PIZZA once.There! You have eleven equally sized, visibly appealing pizza slices!
