There isn't a person out there who wouldn't wonder how things might have been if he or she did things differently.  This is especially true when things don't go the way that you want them to.  You start to wonder if you made the wrong decision.  Like it or not, what's done is done.  When it comes to the woul'ves or could'ves, it reminds me of the song "Would" by Alice In Chains.

It's bad enough that times are hard.  It wouldn't feel that way if things would at least feel like they're going the way you want them to.  Sadly, the fact is that not are times hard, life sometimes can cruel when the plans that you don't come true.  It could be due to a decision or hesitation to do what you want to do.  Either way, the opportunity's lost and you can't get it back.

It's when you loose out on something that you set your heart to that the would'ves and could'ves set in.  The fact is there's nothing you can do about it.  It's all water under the bridge and you to move on. You take stock of what you have and build with as best as you can.  I guest that's what I would do when asked about the would'ves that got away.
