Perhaps this nursery rhyme is about perspective.
The things with which we are surrounded
and the life-events in which we are immersed: are they
burdens or blessings?
disasters or opportunities?
impositions or springboards?
received with resentment or gratitude?
greeted with a groan or a smile?
"It is often hard to distinguish between
the hard knocks in life
and those of opportunity."
Frederick Phillips
