Yesterday, while driving in the car, I noticed some large trees being tossed about in the wind.  I thought this was enlightening.  Consider how remarkably sturdy and unyielding a century-old oak tree looks–immovable and inflexible.  But given the right conditions that tree bends and flexes in the wind. It must, because that is how it survives.  A tree that does not bend will break.

What conditions will bend you?  What situations will break you?
