That reminds me of a "We get Letters" by Michael W. Lucas[0](FreeBSD Journal)

The most important point was:

  It’s uncomfortable. The discomfort is the point.

  Pain is the greatest teacher, but nobody willingly 
  attends her classes.

Learning what's important is only truly possible after loosing it (or not having it in the first place). Having anything granted to us does not prepare for when it's taken away and it's also blinds us on what other possible paths there is.
